Question

Вычислите: -1-2+(-3)+5-(-4)

Answer 1

-1-2+(-3)+5-(-4) = -1 - 2 - 3 + 5 + 4 = -6 + 9 = 3

Answer 2

To compute the expression, follow the order of operations (PEMDAS/BODMAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

1. First, perform the operations inside the parentheses: -1 - 2 + (-3) + 5 - (-4)

2. Next, handle the negative sign in front of (-3): -1 - 2 - 3 + 5 - (-4)

3. Now, resolve the subtraction involving the negative number (-4): -1 - 2 - 3 + 5 + 4

4. Finally, add and subtract from left to right: = (-1 - 2 - 3) + 5 + 4 = -6 + 5 + 4 = -1 + 4 = 3

So, the result of the expression is 3.
