On our lesson - Special Products

Hello children!!! What seems to be the problem regarding our lesson today??? Did you find it hard or you did not understand the lesson....

Anyway, kindly follow the pattern of the following number sentences:

2 X 1 = 2
2 X 10 = 20
2 X 100 = 200
2 X 1 000 = 2 000
2 X 10 000 = 20 000
2 X 100 000 = 200 000

* Remember to multiply the non zero digits first, then add affix the zeroes in the factors
to your answer.

Example: 34 X 200 =
• multiply 34 X 2 = 68
• there are 2 zeroes in the factors, add 2 zeroes to your answer – 6800
• Therefore, 34 X 200 = 6 800

Now try these:

1. 230 X 20 =
2. 30 X 50 =
3. 290 X 400 =
4. 807 X 90 =
5. 7200 X 500 =

Happy solving!!!
