The first couple answerers made a mistake.
The correct answer is -578
(Note: You can save yourself 5 points next time by typing it into Google... It will even put parentheses in to clarify the order of operations...see the link below.)

n.b.: priority of operations
( ) are stronger than * and /
and * and / are stronger than + and -
We have: 2 + 3 -10 * 54 -(99 -56)
= 2 + 3 -10 * 54 -(43)
= 2 + 3 -10 * 54 -43
= 2 + 3 -540 -43
= 5 - 583
= -578
Final answer : -578

2+3-10*54-(99-56)
you do PEMDAS p 4 parentheses, and that is 43mso that leaves you with 2+3-10*54-43 so you then do M for multply and that is 540 so 2+3-540-43 so you then have 5-540-43 then you do the work from there!!
