$-34$

Use PEMDAS (order of operations) to solve!

1. P (parentheses)

$2 * 4 + (8 - 40) - 10$
$= 2 * 4 + (-32) - 10$
$= 2 * 4 - 32 - 10$

There are no exponents (E), so let's move on to M (multiplication).

2. M (multiplication)

$= 2 * 4 - 32 - 10$
$= 8 - 32 - 10$

3. S (subtraction)

$= 8 - 32 - 10$
$= -34$

That's your final answer!

How do you evaluate 2\times 4+ ( 8- 40) - 102\times 4+ ( 8- 40) - 10?
