B I D M A S Brackets Indicies Division Multiplication Addition Subtraction
3 х 6 + 7 = 18 + 7 = 25
7 + 3 х 6 7 + 18 = 25 (do the multiplication first)
7 + 5 + 4 х 9 12 + 36 = 48 (you must do the multiplication first)
67 – 5 х 12 + 4 67 - 60 + 4 = 7 + 4 = 11 (do the multiplication first)
45 – 2 х 12 + 4 45 - 24 + 4 = 21 + 4 = 25 (do the multiplication first)
48÷6+9÷3 8 + 3 = 11 (do the divisions first)
42÷7+7×4 6 + 28 = 34 (do the division and the multiplication first)
(42+9)÷(7-4) 51 ÷ 3 = 17 (do the calculations that are in the brackets first)
(41-5)÷(12-3) 36 ÷ 9 = 4
41-72÷(12-3) 41 - 72 ÷ 9 = 41 - 8 = 33 (do the calculation in the bracket first, then the division)
33-7×(11-8) 33 - 7 × 3 = 33 - 21 = 12 (do the calculation in the bracket first, then the multiplication)
(33-7)×(11-8) 26 × 3 = 78
106 - 5 × 9 - 2 106 - 45 - 2 = 59
19-3 × (9-5) + 22 ÷ 11 19 - 3 × 4 + 2 = 7 = 19 - 12 + 2 = 9
