SUBTRACTION AND MULTIPLICATION
1 I take
4 cupcakes.
I take
4 cupcakes too.
48 cupcakes
How many cupcakes are left?
48 − 2 × 4 =
2 × 4
48 40
Total up the
number of 48 − 2 × 4 = 48 − 8 Then, subtract
cupcakes taken the amount
by 2 persons first. = 40 from the
original number
of cupcakes.
Solve multiplication
first before
subtraction.
48 − 2 × 4 = 40
There are 40 cupcakes left.
2 790 − 8 × 32 = 2
1 Is this method of
810 7 8 2 calculation correct? Discuss.
7 9 0 × 3 2
– 8 1 1
7 8 2 1 5 6 4
+ 2 3 4 6 0
2 5 0 2 4
