Question

Simplify the following expression.

Answer 1

20

Explanation:

Remember PEMDAS!

So first parentheses:

1.6^2 = 2.56

8.7 + 9.3 = 18.

Because that is inside another parentheses you multipy them.

2.56 x 18 = 46.08

Now: 46.08 divided by 1.8 = 25.6

Now subtract:

25.6 - 3.7 - 1.9 which equals 20!

Hope that helped!
