Multiplication

  1. 1. Multiplication<br />By Katie McColly<br />
  2. 2. Key Terms<br />Multiplier: the number or numbers being multiplied<br />Product: the answer<br />Multiplication Signs: x * ∙<br />Example: 2 x 3 = 6<br />2 and 3 are bothmultipliers and 6 is the product<br />
  3. 3. What is Multiplication?<br />Multiplication is nothing but a shortcut for addition!<br />An equation that tells us how many times to add a number with itself<br />
  4. 4. Example #1<br />What is 5 x 2 ?<br />This equation is telling us to add 5with itselftwo times<br />5 + 5 = 10<br />So 5 x 2 = 10<br />
  5. 5. 5 x 2 is the same problem as 2 x 5<br />We would now be adding 2 with itself 5 times!<br />
  6. 6. 2 <br />+ 2<br />+ 2<br />+ 2<br />+ 2<br />= 10<br />
  7. 7. So 5 x 2 = 10<br />
  8. 8. Multiplying by 1<br />Any number multiplied by one is the same number<br />Why???<br />That number is only being added once so it stays the same<br />
  9. 9. For Example<br />3 x 1= ?<br />We are adding 3 only 1 time<br />
  10. 10. So<br />.<br />.<br />.<br />.<br />.<br />
  11. 11. 3<br />+<br />Nothing Else<br />= 3<br />
  12. 12. Meaning that 3 x 1 = 3<br />This works with any number!<br />LIKE…<br />200 x 1 = 200<br />Because 200 + nothing else = 200<br />Or <br />1,000,000 x 1 = 1,000,000<br />
  13. 13. This works in reverse too<br />1 x 3 for example<br />1<br />+1<br />+1<br />=3<br />So 1 x 3 = 3<br />
  14. 14. The Zero Rule<br />Any number multiplied by zero will equal zero<br />WHY???<br />You aren’t multiplying the number by anything<br />
  15. 15. Examples<br />7 x 0 = 0<br />0 x 4 = 0 <br />1 x 0 = 0<br />255 x 0 = 0 <br />Any number x 0 = 0<br />
  16. 16. THE END<br />
