Are the following equations a fact family

9+5=14

15-5=10

4+4=8

15=6+9

Answer: Yes! those are indeed apart of the fact family

Step-by-step explanation:

Notice that 9+5=14 and 5+9=14, thus the first two equations

show that if we add two numbers in any order, we get the same answer.

Notice that 14-9=5 and 9+5=14, so subtraction and addition are

related. Similarly 14-5=9 and 5+9=14

Notice that 14-9=5 and 14-5=9, so if you subtract one of the

members of the fact family from 14, you get the other.
