Question

Put on pair of brackets into each calculation to make it correct

a. 6×7-5 +4= 16

b. -2+24÷12-4=2

Answer 1

a. 6 × (7 - 5) + 4 =

6 × (2) + 4 =

12 + 4 = 16

b. (-2 + 24) ÷ (12 - 4) =

22 ÷ 8 = 2.75

Answer 2

a. (6×7)-(5+4) = 39 - 9 = 16

b. (-2+24)÷(12-4) = 22 ÷ 8 = 2.75 (Alternatively, (-2+(24÷(12-4))) = -2+2 = 0, which is also a correct solution)
