Circle the operation that you do first in each of these calculations: ÷ 2 Division is done before addition. Therefore the first sum you do is 6 ÷ 2 = 3 This leaves us with = x 5 Multiplication is done before subtraction. Therefore, we first do 4 x 5 =20 This leaves us with 32 – 20 =12 6 ÷ (3-1) Brackets are done first. Therefore the first sum you do is 3 -1 = 2 This leaves us with 6 ÷ 2 = 3
