3. As you can see, </span><span>Samantha’s younger brother just turned 36 months old</span> and Fred’s brother is 30 months old. Therefore, you can conclude that Samantha’s younger brother is older than Fred’s brother.
Just use the order of operations. PEMDAS, parentheses, exponents, multiplication, division, addition and subtraction.
In the first problem 2 + 6*3^2, there are no parentheses, so next would be exponents.
There is an exponent so you do that first.
3^2 = 9
Now we have 2 + 6*9
Multiplication is next and it is in the problem, so we do 6*9 = 54
So now we have 2 + 54 which equals 56.
