Answer:

Read explanation

Step-by-step explanation:

The two operations that you will get the same answer for no matter what order you do it is addition and multiplication.

Bonus: Technically, if you had something like 1-2-3 you could rewrite it as 1 + (-2) + (-3) and now it won't matter the order and for something like 1/2/3 you could rewrite as 1 * (1/2) * (1/3) and not it wont matter the order too!

This propetie is called the associative property of addition and multiplication.

In the second question since its addition the order you do it in does not matter.

Why: If you think of it logically adding in a diffrent order than the question does not matter since in the end your still adding the same ammount.

Remember: You can only swap the orders if everything is addition or multiplication and remember your order of operations when using this propety in the years to come.

Hoped this helped, Eddie K.W.

A father is 60 years old and his son is half his age how old was the boy when his father was four times his age
mr Goodwill [35]
F=60, s=60/2=30

(60-x)/(30-x)=4

60-x=120-4x

60+3x=120

3x=60

x=20  

s=30-x

s=30-20

s=10

So the boy was 10 years old when his father was four times his age.
