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

hope this helps
