ORDER OF OPERATIONS BIDMAS 3 2 x 4

ORDER OF OPERATIONS BIDMAS

3 + 2 x 4 = 11 3 + 2 x 4 = 20 (3 + 2) x 4 = 20

Order of Operations Step 1 – Solve brackets Step 2 – Solve multiplication and division from left to right Step 3 – Solve addition and subtraction from left to right

1 2 3 BIDMAS BRACKETS 1 DIVIDE or MULTIPLY 2 from left to right ADD or SUBTRACT from left to right 3

Example 1 2+3 4 BIDMAS Step 1 – No brackets Step 2 – Multiply = 2 + 12 Step 3 – Add = 14

Example 2 BIDMAS 2+3 4 2 Step 1 – No brackets Step 2 – Multiply then divide = 2 + 12 2 =2+6 =8 Step 3 - Add

Example 3 BIDMAS 2 3 -(4+2) =2 3 - 6 =6 -6 =0 Step 1 – Solve Brackets Step 2 - Multiply Step 3 - Subtract

If you have mastered the order of operations so far, let’s add the final piece. . . BIDMAS INDICES (Squares, Cubes & Other Powers)

Order of Operations Revised Step 1 – Solve brackets Step 2 – Solve indices Step 3 – Solve multiplication and division from left to right Step 4 – Solve addition and subtraction from left to right

Example 4 7+ 2 10 BIDMAS 3 Step 1 – No brackets Step 2 – Solve index = 7 + 100 3 = 7 + 300 = 307 Step 3 – Multiply Step 4 – Add

Example 5 BIDMAS 23 ( 48 6 ) - 8 Step 1 – Solve brackets = 23 8 - 8 =8 8 -8 = 64 - 8 = 56 Step 2 – Solve index Step 3 - Multiply Step 4 - Subtract

Example 6 BIDMAS 7 4 + ( 5 – 12 6 2 ) Step 1 – Brackets: divide then subtract = 7 4 + ( 5 – 2 2 =7 4+3 Step 2 – Solve index =7 4+9 Step 3 – Multiply = 28 + 9 2 ) = 37 Step 4 – Add
