Answer:
6.3 - 9.5 = -3.2
4.2 -(-2.6) = 6.8
Explanation:
When you subtract, you are finding the difference. If they have the same sign, you will add them and keep the sign. Example: -5 - 5= -10
If they have different signs, you will subtract them and keep the sign of the higher number. Example: 5 - 6 = -1. or 3 - 1 = 2. So, for 6.3 - 9.5, you will subtract the smaller number from the larger number and keep the sign of the higher.
For the second equation: 4.2 -(-2.6) you use PEMDAS. First, take care of the parenthesis. -(-2.6)= +2.6
So you rewrite it as:
4.2 + 2.6= 6.8
PEMDAS is the order of operations. Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
Remember to go left to right.
