Find 2 numbers that are not common multiples of 5 and 2

• Multiples of 5: 5, 10, 15, 20, 25, …

• Multiples of 2: 2, 4, 6, 8, 10, 12, …

• Common multiples of 5 and 2: 10, 20, 30, 40, … (multiples of 10)

So any number not a multiple of 10 would work.

Insert brakets to make these calculations correct.

8 + 6 × 2 = 28

12 − 4 × 2 + 6 = 16

5 + 3 × 4 − 2 = 15

(8 + 6) × 2 = 28

12 − (4 × 2) + 6 = 16

5 + (3 × 4) − 2 = 15
