i m doing a worksheet with negatives and parentheses...they have examples to explain how to do it:
Ex. (-6)-(-41)+(-18)-35
= -6+41-18-35=35-18-35=-18
i understand that part
how do you do this two?
(-2)-(-6)-4= -2+6-4=-_+6=
-48+(-25)-(-13)+12=
in the first problem, there is a blank that u have to fill in first
help me please
(-2)-(-6)-4= -2+6-4=-_+6=
-2-4 = -6
so
-6+6 = 0
in other words
(-2)-(-6)-4= -2+6-4=-6+6= 0
================================
-48+(-25)-(-13)+12= - 48 - 25 + 13 + 12
Sure! Let's break down these two problems step by step:
1. (-2) - (-6) - 4
To solve this expression, we use the rule that subtracting a negative number is the same as adding a positive number. So, we can rewrite the expression as:
(-2) + 6 - 4
Now, just follow the order of operations (PEMDAS/BODMAS) which states that we need to perform any parentheses first, then exponents, followed by multiplication and division from left to right, and finally addition and subtraction from left to right.
Since there are no parentheses or exponents in this expression, we move on to subtraction and addition from left to right:
(-2) + 6 = 4
4 - 4 = 0
Therefore, the answer is 0.
2. -48 + (-25) - (-13) + 12
Again, let's start by simplifying the expression using the rule that subtracting a negative number is the same as adding a positive number:
-48 + (-25) + 13 + 12
Now, following the order of operations, we perform addition and subtraction from left to right:
-48 + (-25) = -73
-73 + 13 = -60
-60 + 12 = -48
Therefore, the answer is -48.
In summary, to solve these expressions, you need to remember the rule for subtracting a negative number and follow the order of operations. Always make sure to perform addition and subtraction from left to right.
I hope this helps! Let me know if you have any further questions.
