Multiplicaciones
Piensa antes de resolver los siguientes problemas de multiplicaciones.
|
| A | B |
|---|
| 25 x 10 = | 250 |
| 39 x 10 = | 390 |
| 200 x 5 = | 1,000 |
| 42 / 7 = | 6 |
| 72 / 9 = | 8 |
| 900 x 2 = | 1,800 |
| 25 x 4 = | 100 |
| 75 + 25 = | 100 |
| 7 + 3 = | 10 |
| 27 + 23 = | 50 |
| 50 / 2 = | 25 |
| 100 - 25 = | 75 |
| 1,000 - 900 = | 100 |
| 2,000 + 2,000 = | 4,000 |
| 900 - 500 = | 400 |
| 325 - 305 = | 20 |
| 20 x 20 = | 400 |
| 50 x 50 = | 2,500 |
| 2,500 - 1,500 = | 1,000 |
| 999 - 888 = | 111 |
