**2.2 - Text Book**

Question: #16

Bella is more

**comfortable**working with integers than with**positive and negative decimal numbers**. This is her way of understanding -4.3 + 2.5 .

**-4.3 is -43/10 or -43 tenths**

**2.5 is 25/10 or 25 tenths**

**-43 tenths + 25 tenths is -18 tenths**

**-18 tenths is -18/10 or -1.8**

**So, -4.3 + 2.5 = 1.8**

A ) Use Bella's method to determine 6.1 + (-3.9).

B) How could you modify Bella's method to determine 1.25 -3.46?
