can you help me with this please
-19-12+2-(-21)+11-(-5)
- 19 - 12 + 2 - ( -21 ) + 11 - ( - 5 ) =
- 19 - 12 + 2 + 21 + 11 + 5 =
2 + 21 + 11 + 5 - 19 - 12 =
39 - 19 - 12 =
20 - 12 = 8
PEMDAS
parenthesis, exponent, multiply, divide, add, subtract (these are the order of operation follow them in that order like bosnan did)
he multiply the parenthesis by whats nexxt to it first and then added and subtract everything
Of course, I'd be happy to help you with this expression: -19 - 12 + 2 - (-21) + 11 - (-5).
To simplify this expression, let's break it down step by step:
Step 1: Simplify the double negative (-21). To remove the double negative, we can change it to a positive number, so -(-21) becomes +21.
Step 2: Simplify the expression by combining like terms. Start by removing the parenthesis:
-19 - 12 + 2 + 21 + 11 - (-5)
Step 3: Simplify each term:
-19 - 12 = -31
+2 = 2
+21 = 21
+11 = 11
-(-5) = +5
Now, we have:
-31 + 2 + 21 + 11 + 5
Step 4: Add all the terms together:
-31 + 2 + 21 + 11 + 5 = -31 + 2 + 21 + 11 + 5 = -31 + 38 + 5 = -6
Therefore, the simplified expression -19 - 12 + 2 - (-21) + 11 - (-5) is equal to -6.
