3. 4. About ArithmetEQ <ul><li>Consist of a board with premium squares </li></ul><ul><li>150 tiles that are printed on both sides (numbers or operators on one side, equal sign on the other side) and are placed in the bag </li></ul><ul><li>Numbers (0 – 9) </li></ul><ul><li>Mathematical Operators </li></ul>
4. 5. About ArithmetEQ <ul><li>Mathematical Operators </li></ul><ul><li> - Addition - Subtraction </li></ul><ul><li> - Multiplication - Division </li></ul><ul><li> - Power - Fraction </li></ul><ul><li> 3 ^ 2 = 9 1 Γ 2 Γ 3 = </li></ul><ul><li> - Square Root - Brackets </li></ul><ul><li> 3 (2 + 4) = 1 8 </li></ul><ul><li>- Decimal Point </li></ul>
5. 6. How to play the game <ul><li>Each player will draw 7 </li></ul><ul><li>tiles from the bag. </li></ul><ul><li>The 1 st player will use 4 or more tiles to form an equation on the board to read either across (left to right) or down, with a tile on the centre square </li></ul>
6. 7. How to play the game (cont..) <ul><li>After an equation is placed on the board, the player will replace the number of tiles that are used from the bag and place them back on his rack. </li></ul><ul><li>Play in sequence and on each turn, the players have a choice of exchanging the tiles, passing or placing an equation on the board. </li></ul><ul><li>All tiles played in any one turn must be placed in each row across or one column down the board. </li></ul>
7. 8. How to play the game (cont..) <ul><li>If the tiles touch each other in adjacent row, they must form complete equations. </li></ul>  
8. 9. How to play the game (cont..) <ul><li>The game ends </li></ul><ul><li>when all the tiles have been drawn from the bag and 1 of the players has used up all the tiles in his rack. </li></ul><ul><li>Or </li></ul><ul><li>all the players have passed once in the same turn. (Exchange of tiles is not a pass) </li></ul>
9. 10. Take Note… <ul><li>Always ensure that there are 7 tiles on your rack as long as there are still tiles left in the bag. </li></ul><ul><li>Any player may use their turn to exchange ONE or ALL their tiles on their rack. They will then miss a turn and have to wait for the next turn to play. </li></ul>
10. 11. Take Note… (cont..) <ul><li>Each player has to form an equation during his turn. </li></ul><ul><li>- 1 st player places “ 2 + 3 = 5”. </li></ul><ul><li>- 2 nd player places “5 =” in front of the tile “2”. </li></ul><ul><li>This is correct as “5 = 2 + 3” is an equation. </li></ul><ul><li>- 3 rd player places “= 5 . 0” after “= 5”. </li></ul><ul><li>This is not allowed as 5 = 5.0 is not an equation. </li></ul>  
11. 12. Take Note…(cont..) <ul><li>Some examples of tiles arrangements. </li></ul><ul><li>Arrangements that are allowed. </li></ul>
12. 13. Take Note…(cont..) <ul><li>Some examples of tiles arrangements. </li></ul><ul><li>Arrangements that are not allowed </li></ul><ul><li>or </li></ul>
13. 14. Scoring <ul><li>The score value of each number or operators are indicated by a number at the bottom of the tile. </li></ul><ul><li>The blank tiles has no score value but can be used as any number (0 – 9) desired. </li></ul><ul><li>There are 6 blank tiles altogether. </li></ul>
14. 15. Scoring (Cont..) <ul><li>Multiply by 2 to the score on the tile placed above it and add up the total score </li></ul><ul><li>Multiply by 3 to the score on the tile placed above it and add up the total score </li></ul><ul><li>Add up the score on the tiles and multiply by 2 </li></ul><ul><li>Add up the score on the tiles and multiply by 3 </li></ul>The following shows the premium squares on the board.
15. 16. Scoring (Cont..) <ul><li>The score for a turn is calculated by adding all the values of the number on the tiles plus the premium values resulting from placing on the tiles on the premium squares. </li></ul><ul><li> Total Score </li></ul><ul><li> = (1 + 2 + 1 + 1 + 1)  3 </li></ul><ul><ul><ul><ul><ul><li> = 18 </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>(The tile “3” falls on the </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>“ 3 x eqn” square. Hence </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>the total score will be the </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>sum of all the values </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>multiplied by 3) </li></ul></ul></ul></ul></ul>
16. 17. Scoring (Cont..) <ul><li>Number and equation premiums count only on the turn in which they are played. On later turns, numbers already played on premium squares will only be counted at face value. </li></ul><ul><li>The 2 nd player placed </li></ul><ul><li>“ 6 x” and “= 8” </li></ul><ul><li>Total score for the 2 nd player </li></ul><ul><li>= 1 + 2 + 1 + 1 + 1 </li></ul><ul><li>= 6 </li></ul><ul><li>(Tile “3” on the premium </li></ul><ul><li>square is placed by the </li></ul><ul><li>1 st player, hence the sum </li></ul><ul><li>of the score x 3 will not </li></ul><ul><li>applicable to the 2 nd player) </li></ul>
17. 18. Scoring (Cont..) <ul><li>The 3 rd player placed “2 +” and </li></ul><ul><li>“ + 3 = 6” </li></ul><ul><li>Total score for the 2 nd player </li></ul><ul><li>= 1 x 2 + 2 + 2 + 1 x 2 + 1 + 1 </li></ul><ul><li>= 10 </li></ul><ul><li>(Tile “2” and “3” falls on the </li></ul><ul><li>“ 2 x term” square, hence the </li></ul><ul><li>score value of these 2 tiles will </li></ul><ul><li>be multiplied by 2 and then add </li></ul><ul><li>up all the sum to find the total </li></ul><ul><li>score.) </li></ul><ul><li>The 2nd player placed a blank tile which represent the </li></ul><ul><li>number “1”, hence the number on this particular blank </li></ul><ul><li>tile will be fixed as “1” throughout the game. </li></ul>
18. 19. Scoring (Cont..) <ul><li>Bonus Score: </li></ul><ul><li>If the player uses ALL the tiles on his rack in a single turn, in addition to the regular score for his turn, he scores an extra 50 points </li></ul>
19. 20. Scoring (Cont..) <ul><li>Unplayed tiles: </li></ul><ul><li>When the game ends, the final score of each player is reduced by the sum of all his unplayed tiles. </li></ul><ul><li>If one player has used up all his tiles, his score is increased by the sum of all the unplayed tiles of all other players. </li></ul>
20. 21. Scoring (Cont..) <ul><li>The player with the highest final score wins the game. </li></ul><ul><li>In case of a tie, the player with the highest score before adding or deducting unplayed tiles wins. </li></ul><ul><li>Decision of the judges is final. </li></ul>
21. 22. Latest Update! <ul><li>Disallowed arrangements (those not found in earlier slides) 1. 6-4=2/0/2  Allowed arrangements (those not found in earlier slides) 1. [2] [sqrt][3][=][2] [X] [sqrt 3] 2. [7][/][1][=][7] becomes [7][7]/[1][=][7][7] 3. [0][divide][1][2][3][4][5][=][0] 4. [0][/][1][2][3][4][5][=][0] </li></ul>
