I must simplify this expression. Am I correct?
-4[-25-(9-3)].
I first subtract within the parentheses first
-4[-25-(-6)]
-4-(-31) = 27
-4(-25-(6))
-4 (-25-6)
-4 (-31)
124
I see my mistake. I was supposed to multiply 31 into 4.
Thank you so much!
To simplify the expression -4[-25-(9-3)], you correctly started by evaluating the subtraction within the parentheses first. However, there seems to be a mistake in your calculations.
Let's break it down step by step:
1. First, simplify the expression within the inner parentheses: 9 - 3 equals 6.
-4[-25 - 6] = -4[-31]
2. Next, simplify the expression within the outer brackets: -25 - 6 equals -31.
-4[-31]
3. To simplify further, multiply -4 by -31. Since both numbers are negative, the product will be positive:
-4 × -31 = 124
Therefore, the simplified expression is 124.
