**Multiplication of numbers 1 to 10 **

**Examples**

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

**Multiplication of 2-digit numbers by 1-digit numbers**

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

**Multiplication word problems**

- In a box of juice there are 12 packets. How many packets are there in

10 boxes of juice?
