Question

3^3 - 5 x 9 + 6 - 29

Answer 1

To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

REMEMBER: IF A STEP IS NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS

Exponent...

3³ - 5 x 9 + 6 - 29

3³ = 27

27 - 5 x 9 + 6 - 29

Multiplication...

27 - 5 x 9 + 6 - 29

5 × 9 = 45

27 - 45 + 6 - 29

Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows addition before subtraction, you must remember that addition and subtraction are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right. In this case that would be subtraction first then addition then subtraction again. NOTE: This rule also applies when you are dealing with multiplication and division in the same expression

27 - 45 + 6 - 29

27 - 45 = -18

-18 + 6 - 29

-18 + 6 = -12

-12 - 29

= -41

Answer 2

Answer:

-41

Step-by-step explanation:

3^3-5x9+6-29

calculate exponents 3^3=27

now write as; 27-5x9+6-29

now multiply and divide (left to right) 5x9=45

now rewrite as 27-45+6-29

now add and subtract(left to right) 27-45+6-29= -41
