How the heck do you do this?!

Dennis_Churaev [7]

Use PEMDAS to figure out the order of operations:

Parentheses
Exponents
Multiplication/Division
Addition/Subtraction

Solve (-4 + -6) first, as this is in parentheses:

$-4 + -6 = -10$

$10 - 5.3 * -10$

Solve 5.3 * -10 next, as this is multiplication:

$5.3 * -10 = -53$

$10 - -53$

Now we can solve the equation:

$10 - -53 = 63$

The answer is 63.
