  3. 3. INTRODUCTION There are two types of numbers namely: Whole / Natural Numbers Integers Adjex Academy 3
  4. 4. WHOLE NUMBERS Natural number is another name for the Whole number. There are ten numbers. There are only positive numbers They include 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Adjex Academy 4
  5. 5. Whole Numbers Combination of the whole numbers make more numbers 10 = Ten 101= One hundred and one 1000 = One thousand Adjex Academy 5
  6. 6.  ‘0 < 5’ means zero is less than five  ‘5 > 0’ means five is greater than zero Adjex Academy 6
  7. 7. INTEGERS They are made up of Positive whole numbers Zero Negative whole numbers Adjex Academy 7
  8. 8. -3 < -1 -1 > -3 1 < 3 3 > 1 Adjex Academy 8
  9. 9. TERMS USED IN SOLVING Sum Difference Product Quotient Adjex Academy 9
  10. 10. SUM It means to add ‘+’ Plus is the sign for addition 2 + 2 = 4 Adjex Academy 10
  11. 11. DIFFERENCE To subtract ‘−’ minus is the sign to subtract 4 − 2 = 2 Adjex Academy 11
  12. 12. PRODUCT It means to multiply ‘×’ times is the sign to multiply 2 × 3 = 6 Adjex Academy 12
  13. 13. QUOTIENT It means to divide ‘÷’ or ‘/’ This is the sign to divide 6 ÷ 2 = 3 Adjex Academy 13
  14. 14. THINGS TO NOTE Subtract 8 from 9 It means 9 – 8 = 1 But Subtract 9 from 8 It means 8 – 9 = -1 When we multiply we do so from right to left but when we divide we do so from left to right Adjex Academy 14
  15. 15. COMMUTATIVITY This means two integers can be added or multiplied either ways. 2 + 3 = 5 3 + 2 = 5 2 × 3 = 6 3 × 2 = 6 But 3 – 2 = 1 2 – 3 = -1 6 ÷ 2 = 3 2 ÷ 6 = 1⁄3 Adjex Academy 15
  16. 16. ASSOCIATIVITY Three or more integers when added or multiplied in either way does not affect the result. Not possible for subtraction or division 3 + 4 + 5 = 7 + 5 = 12 5 + 3 + 4 = 8 + 4 = 12 2 × 1 × 3 = 2 × 3 = 6 3 × 1 × 2 = 3 × 2 = 6 Adjex Academy 16
  17. 17. TIPS USED IN SOLVING Simplification tips ‘+’ × ‘+’ = + ‘+’ × ‘−’ = − ‘−’ × ‘+’ = − ‘−’ × ‘−’ = + Solve 2 + (+2) = 2 + 2 = 4 3 – (−3) = 3 + 3 = 6 4 + (−3) = 4 − 3 = 1 Adjex Academy 17
  18. 18. BODMAS BODMAS is an acronym used in solving. B = Bracket O = Of D = Division M = Multiplication A = Addition S = Subtraction Adjex Academy 18
  19. 19. Bodmas (2 + 2) − 1 + 3 × 4 Using BODMAS solve Bracket first (2 + 2) − 1 + 3 × 4 = (4) − 1 + 3 × 4 Then multiplication = 4 − 1 + 12 Then addition = 4 – 13 And finally subtraction = −9 Adjex Academy 19
