It cannot be solved as written. We need to know 2% of what. The way the equation is written, it is like asking 2 + 2 - 0 - .02 X ?

We have to know what the percentage is of. The part to the left is obviously 4 (2 + 2 - 0 = 4) but again we do not know what the 2% is suppose to refer to. If it was suppose to be 2% of 4, then it should have been written 2 + 2 - 0 - 2%(2 + 2 - 0) or 2% of 2 + 2 - 0, which would be .08, which when subtracted from 4 would give you 3.92

I'm actually going to go a divergent route and say that the answer is 4. Two percent of 0 is 0. The reasoning behind this is how I view order of operation. I view the the statement as a triple conditional. 0-2% is a paired conditional, with 2% being that of 0, 2+2 = 4 is a paired condition, and the sum of 2 + 2 and the difference of 0- 2% is the last conditional. Under this rule set, (2+2) - (0 - 2%)= 4. Logically, I'm making the assumption that the constraints of the 2% are tied to the zero, otherwise there is no answer, and the problem would not be a simple solution.

Simple means that, in my mind, there are no decimal points. There are no complicated finaglings with determining the outcome by multiplying 2% times the sum of 2 + 2 or as a reflection of 100. I'm simply limiting the constraints to the actual equation, and then defining what 2% is within equation proper prior to the end of the order of operations. I hope that my reasoning makes sense for why I've come to the answer of 4 as the ultimate answer to this equation.

What you've presented here seems simple yet it is tricky because you do not specify 2% of what. If we assume that 2% is just .02 then the answer becomes 3.98. However if we assume that it is 2% of 4 the answer becomes 3.92. But it could be 2% of any number really, which again you've not specified so we can only guess.

Given the lack of parenthesis in the equation, the most valid way to solve the problem is in order. The convention in equations without parenthesis is solve all plus and minus signs in the order they appear in the equation; therefore:

2 + 2 = 4
4 - 0 = 4
4 - 2% = 4 - (4 x 0.2) = 4 - 0.08 = 3.92

Add 2+2=4 then subtract 0 from 4 (4-0=4); 2% is same as 0.02 because your Dividing 2 with a 100 so you count decimal places from right hand side of 2. two steps to the left so you get (0.02) and after that subtract this from 4 4-0.02=3.98 as our answer. Hope it will help you.

Firstly, you should know that the decimal form of 2% is 0.02. Therefore this just becomes a simple addition and subtraction equation.
2+2=4
4-0=4
4-0.02= 3.98

Hence our final answer is 3.98

(2+2-0)-2%

(2+2-0)*0.02

4*0.02= 0.08

4-0.08=3.92

Therefore your answer is 3.92

Hope this helps! Have a good day!

I think you should convert the 2% first and then set it down like a normal equation. 2+2-0-0.02
4-0-0.02=3.98

...
C

2 + 2 - 0 - 2/100 = 2 + 2 - 0 - 0.02 = 4 - 0.02 = 3.98

3.98.
