PROBLEM

Cube -5 and subtract from -18. Simplify: -18 - (-5)^3.

STEP 1

Assumptions1. The number to be cubed is -5. The number from which the cubed result will be subtracted is -183. The order of operations (PEMDAS/BODMAS) will be followed, where/B - Parentheses/Brackets first/O - Exponents/Orders (ie Powers and Square Roots, etc.)
MD - Multiplication and Division (left-to-right)
AS - Addition and Subtraction (left-to-right)

STEP 2

First, we need to cube -5. Cubing a number means multiplying the number by itself twice.
Cubeof5=(5)×(5)×(5)Cube\, of\, -5 = (-5) \times (-5) \times (-5)

STEP 3

Calculate the cube of -5.
Cubeof5=(5)×(5)×(5)=125Cube\, of\, -5 = (-5) \times (-5) \times (-5) = -125

STEP 4

Now that we have the cube of -, we can subtract this from -18.
Result=18(125)Result = -18 - (-125)

STEP 5

Remember that subtracting a negative number is the same as adding a positive number.
Result=18+125Result = -18 +125

SOLUTION

Calculate the result.
Result=18+125=107Result = -18 +125 =107The numerical expression is107.
