In this worksheet, you must increase or decrease a number by 0.1 or 0.01.

When we add 0.01 or subtract 0.01 from a number it is the hundredths column that needs to be considered.

**Examples**

5.36 + 0.01 = 5.37

5.39 + 0.01 = 5.40 = 5.4

5.36 - 0.01 = 5.35

5.4 - 0.01 = 5.40 - 0.01 = 5.39

When we add 0.1 or subtract 0.1 from a number it is the tenths column that needs to be considered.

**Examples**

5.36 + 0.1 = 5.46

5.99 + 0.1 = 6.09

5.36 - 0.1 = 5.26

5 - 0.1 = 5.0 - 0.1 = 4.9
