BODMAS B rackets first 3 x ( 9 – 2 ) = 3 x 7 = 21 M rder or Of 2 x 3² = 2 x 9 = 18 O ivision 12 – 8 ÷ 2 = 12 – 4 = 8 D ultiplication 30 – 4 x 6 = 30 – 24 = 6 A S ddition – 2 = = 13 ubtraction 23 – 8 – 5 = 15 – 5 = 10 Division or Multiplication …… whichever comes first Addition or Subtraction …… whichever comes first
x x 5 B O D M A S No Order, Of, Other No Brackets No Division Yes = 3 + = 23
x 9 – 3 x x 4 B O D M A S No Order, Of, Other No Brackets No Division Yes = = x
9 12 – B O D M A S No Order, Of, Other No Brackets No Division No Multiplication = 5 + = 14 Yes ….. BUT there is a subtraction before this Yes ….. AS whichever comes first from Left to Right
20 10 x 2 ÷ 4 10 x 2 ÷ 4 B O D M A S No Order, Of, Other No Brackets Yes but there is a multiplication before this Do 1 st to make sum easier. BODMAS could be BOMDAS = 4 ÷ = 5

10 ( ) x 2 ) x 2 B O D M A S Yes = = (7 x 2
79 ( ) x ( 9 – 2 ) ) x B O D M A S Yes = = (5( 9 -) 2 x
8 5 x ( x 2 ) ÷ B O D M A S Work out this sum first = ( x 56x 2)7 ÷ Multiplication +( x 56 )7 ÷
148 5 x ( x 2 ) ÷ B O D M A S Use BODMAS with each line = ( x 56x 2)7 ÷ Add then remove brackets +( x 56 )7 ÷ x 5 7 ÷ =
x ( x 2 ) ÷ BODMAS = ( x 56x 2)7 ÷ +( x 56 )7 ÷ x 5 7 ÷ = Division and Multiplication are of equal priority Dividing first will make this sum easier = x 5 = 10
