Izzy writes subtraction equations represented by the bar model. Which equation is NOT correct?

• 60 − 32 = 28

• 32 = 60 − 28

• 28 = 60 − 32

• 32 − 28 = 60

Answer explanation

Izzy made a mistake with 32 − 28 = 60 as the difference is bigger than the minuend.

Match up the addition and subtraction equations.

• 24 = 20 + 4

• 24 − 4 = 20

• 4 + 24 = 28

• 28 − 4 = 24

• 28 = 14 + 14

• 28 − 14 = 14

• 20 + 8 = 28

• 28 − 8 = 20

Answer explanation

20 + 8 = 28 can be rearranged into the subtraction equation 28 − 8 = 20
