E - Exponents
D - Divide
M - Multiply
A - Addition
S - Subtraction
When answering this question, you must start with brackets. Since there are no brackets, you must go on to the exponents. Which is in this case, 8^2 and 2^2. You must start from left to right so you start with 8^2.
8 x 8 = 64
When that's done, you have to do the other exponent.
2 x 2 = 4
Then you have to divide. Which is the 64 ÷ 16.
64 ÷ 16 = 4
Then you have 4 - 4.
And then you just have to subtract that.
The answer you should get is 0.
