I got. -20
10/5 + 8+(-3) /5 -4=
I got -1
Your third one is right. I'm not sure about the fourth.
The first two are wrong.
Sure, I can check your answers for you!
Let's go through each expression:
1. 3 + 2(4) - 3 + 4(-3)
To solve this, we need to follow the order of operations, which is parentheses, exponents, multiplication/division (from left to right), and finally addition/subtraction (from left to right).
First, we have 2(4) = 8, and 4(-3) = -12.
The expression becomes: 3 + 8 - 3 + (-12)
Next, we add or subtract from left to right:
3 + 8 = 11, then subtract 3: 11 - 3 = 8
Finally, we add: 8 + (-12) = -4
So, the correct answer for the first expression is -4.
2. 3 + 4 - 2 - 5 + 3 - 6 - 8
Again, following the order of operations, we start with addition/subtraction from left to right:
3 + 4 = 7, then subtract 2: 7 - 2 = 5
Next, we subtract 5: 5 - 5 = 0
Continuing, we add 3: 0 + 3 = 3
Then we subtract 6: 3 - 6 = -3
Finally, we subtract 8: -3 - 8 = -11
So, the correct answer for the second expression is -11.
3. 4 - 3(2 + 6)
We have parentheses here, so we evaluate what's inside first:
2 + 6 = 8
Now, we multiply: 3(8) = 24
Lastly, we subtract: 4 - 24 = -20
So, the correct answer for the third expression is -20.
4. 10/5 + 8 + (-3) / 5 - 4
Let's apply the order of operations:
First, we divide: 10/5 = 2, and (-3) / 5 is equivalent to -3/5.
The expression becomes: 2 + 8 + (-3/5) - 4
Next, we add or subtract from left to right:
2 + 8 = 10, then add -3/5: 10 - 3/5
Lastly, we subtract 4: (10 - 3/5) - 4
To simplify further, we need to find a common denominator for the fractions:
(10 - 3/5) - 4 = (50/5 - 3/5) - 4 = (47/5) - 4
Now, we need to subtract fractions with the same denominator:
(47/5) - 4 = 47/5 - (20/5) = 27/5
So, the correct answer for the fourth expression is 27/5.
