|---|---|---|---|
| \(35 \times 10 = 350\) \(33 \times 11 = 363\) \(363 - 350 = 13\) OR \(10 \times (35 - 33) = 20\) \(33 - 20 = 13\) | 13 | 3 | M1 \(35 \times 10\) (= 350) or \(33 \times 11\) (= 363) M1 (dep) finding the difference in their totals e.g. ‘363’ – ‘350’ A1 cao OR M1 \(10 \times (35 - 33)\) (=20) or \(11 \times (35 - 33)\) (=22) M1 (dep) 33 − ‘20’ or 35 − ‘22’ A1 cao |
