Multiplication of numbers 1 to 10

Examples

1. 0 × 6 = 6 i.e 0 into 6places – 0+0+0+0+0+0= 0
2. 7 × 6=42- 7+7+7+7+7+7=42
3. 6 × 4=24- 6+6+6+6=24
4. 10 × 6=60-10+10+10+10+10+10=60
5. 6 × 8=48- 6+6+6+6+6+6+6+6=48
6. 5 × 2=10- 5+5=10

Multiplication of 2-digit numbers by 1-digit numbers

1. 23×2=46; 2 goes into 3 gives 6 and into 20 gives 40
2. 20×4=80
3. 43×4=172
4. 11×8=88
5. 14×9= 126

Multiplication word problems
