The total number of stickers :

Page 1 : 28

Page 2 : 24

Page 3 : 72

Page 4 : 48

Further explanation

There are several properties in integer multiplication operations

  • 1. closed property

Multiplication between integers will produce integers too

  • 2. commutative property

a x b = b x a

  • 3. associative property

ax (bxc) = (axb) xc

  • 4. identity

ax1 = 1 x a = a

  • 5. distributive  property

* addition

ax (b + c) = axb + axc

* substraction

ax (b-c) = axb - axc

We can use facts to solve multiplication problems

for example :

6 x 7 = (5 x 7) + ( 1 x 7) = 42

we can break facts with 6 into  5s and 1s facts from multiplication above

julia puts her stickers into arrays in an album

From picture (attached) we can find the total number of stickers on each page with 1s,2s,3s and 5s facts

  • Page 1 : 4 x 7 = (2 x 7) + ( 2 x 7) = 14 + 14 = 28
  • Page 2 : 4 x 6 = (1 x 6) + (3 x 6) = 6 + 18 = 24
  • Page 3 : 8 x 9 = ( 3 x 9) + (5 x 9) = 27 + 45 = 72
  • Page 4 : 8 x 6 = (3 x 6) + (5 x 6) = 18 + 30 = 48
