40 questions
Reasoning: 36/40=0.9
Remember to follow PEMDAS (Parenthesis, Exponents (&roots), Multiplication, Division, Addition, Subtraction)
20-3•6+10²+(6+1)•4
First, solve the parenthesis
6 + 1 = 7
20 - 3 x 6 + 10² + 7 x 4
Next, solve the exponent
10² = 10 x 10 = 100
20 - 3 x 6 + 100 + 7 x 4
Next, solve each multiplication. Remember to bring your sign.
-3 x 6 = -18
7 x 4 = 28
20 - 18 + 100 +28
Simplify
(20 - 18) + (100 + 28)
2 + 128
130
130 is your answer
