Question

Looking for someone to walk me through solving the equation rather than just giving me the answer. Simplify the expresion

-4^2-7*4*-2-1^3

Answer 1

39

Explanation:

First, let's make the equation clearly read:

`{ - 4}^(2) - 7 * 4 * - 2 - {1}^(3)`

Second, prioritize to calculate any multiplication or division, since this case is multiplication, then:

`- {4}^(2) - (7 * 4 * - 2) - {1}^(3)`

`- {4}^(2) - (28 * - 2) - {1}^(3)`

`- {4}^(2) - ( - 56) - {1}^(3)`

Third, settle any sign left in the equation before calculating:

`- {4}^(2) + 56 - {1}^(3)`

Fourth, simplify the above equation to:

`- ( {4} * 4) + 56 - (1 * 1 * 1)`

`- 16 + 56 - 1`

Answer is 39

Hope it helps. Thanks!
