Answer 10

P- You first begin by solving anything that is inside a parenthesis. If there isn't anything inside a parenthesis, move to E.
E- Then, you solve the exponents. Once again, if there are not any exponents move on.
M- multiply
D- divide
A- add
S- subtract

Ok let me show you how

Answer 23

Fairy's on the right track. It is ESSENTIAL that you follow Order of Operations rules here.

Answer 24

Since there're no numbers in a parenthesis and because there are no exponents, you would begin by multiplying.
90 • 4 – 14 ÷ 2 + 102 ÷ 5 • 2
The two multiplication pairs are 90 by 4 and 5 by 2
So after multiplying your equation will look like this:
360 - 14 ÷ 2 + 102 ÷ 10
The next thing in the order of operations is dividing
So you would divide 14 by 2 and 102 by 10.
The equation will then look like this:
360 - 7 + 10.2
Next, you add 10.2 and 7:
360 - 17.2
And finally subtract.
342.8 is your answer
