Use PEMDAS to figure out the order of operations:

Parentheses
Exponents
Multiplication/Division
Addition/Subtraction

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

[tex]-4 + -6 = -10[/tex]

[tex]10 - 5.3 * -10[/tex]

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

[tex]5.3 * -10 = -53[/tex]

[tex]10 - -53[/tex]

Now we can solve the equation:

[tex]10 - -53 = 63[/tex]

The answer is 63.

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

Parentheses is 1st

-4 + -6 = -10

Then is multiplication. 

-10 × 5.3 = -53

At last, subtract

10 - (-53) is the same as: 10 + 53

10 + 53 = 63

Your answer is 63

Hope this helps :)
