Here, v - w would be (6-1, 3-[-2]), or (5, 5).
I don't believe you need the word "result" here. At first I thought you'd meant "resultant." Here you're finding the "difference" v less w.
Should be 22%. When trying to convert a decimal to a percent just move the decimal point two places to the right. Ex: .07 = 7% or 1.11 = 111%
Using pemdas you can solve it. Pemdas stands for parentheses, exponents, multiply, divide, add, and subtract. So you look at the problem and you look if there’s any parentheses which is not so then you move onto exponents which there is. Two to the third power is equal to 8. The problem then becomes 28+87/3•8
Then you look for multiplication. 3•8=24
It’s now 28+87/24
Next is division so you do 87/24 = 3.6
Now it is 28+3.6=31.6
The answer is 31.6
