Answer:

#-4.7 +3.16 = -1.54#

Explanation:

There are 2 aspects to consider here...

  • When you are adding or subtracting decimals, make sure that the decimal points are aligned....
  • adding positive and negative numbers.

If the signs are different, subtract the numbers and keep the sign of the 'bigger'

#-4.70#
#ul(+3.16)#
#ul(-1.54)#

This can also be written as:

#-4.7 +3.16 = -1.54#
