Order of Operations (BIDMAS): Inserting brackets Silent Teacher Intelligent Practice Narration Your Turn Insert brackets to make these calculations true: 8 + 4 x 5 – 2 = 20 8 + 4 x 5 – 2 = 58 8 + 4 x 5 – 2 = 26 Practice

Insert brackets to make this true 8 + 4 x 5 – 2 = 20 Worked Example Your Turn Insert brackets to make this true 8 + 4 x 5 – 2 = 20 8 + 4 x 5 – 2 = 58 8 + 4 x 5 – 2 = 26 8 + 4 x 5 – 2 = 36 Insert brackets to make this true 7 + 3 x 5 – 1 = 49 7 + 3 x 5 – 1 = 40 7 + 3 x 5 – 1 = 19 7 + 3 x 5 – 1 = 21

Insert brackets to make these true 8 + 4 x (5 – 2) = 20 Worked Example Your Turn Insert brackets to make these true 8 + 4 x (5 – 2) = 20 (8 + 4) x 5 – 2 = 58 8 + (4 x 5) – 2 = 26 (8 + 4) x (5 – 2) = 36 Insert brackets to make these true (7 + 3) x 5 – 1 = 49 (7 + 3) x (5 – 1) = 40 7 + 3 x (5 – 1) = 19 7 + (3 x 5) – 1 = 21
