Thhtu 1111 x10 In the decimal system, each column has numbers 10 x bigger than the next one 1101001000

3
Thhtu x10 Lets try it with another number! 3 3 0 x10 3 0 0 x10 3 0 0 0

4
Thhtu 6 60 x10 If we multiply 6 by ten it will move into the next column We must put a 0 in the empty units column to hold the place – 6 x 10 = 60

5
Lets try with some other numbers 20200 330 23 x 10 = 230 Thhtu 23 Dont forget to add the zero in the empty column!

6
Lets try these together! 48 x 10 = 93 x 10 = 134 x 10 = 256 x 10 = 889 x 10 = 480 930 1340 2560 8890 Were you right?

7
Thhtu 6 600 If we multiply 6 by a hundred it will move up two columns We must put a 0 in the empty columns to hold the place – 6 x 100 = 600

8
Lets try these together! 8 x 100 = 15 x 100 = 28 x 100= 134 x 100 = 267 x 100 = 800 1500 2800 13400 26700 Were you right?
