PEMDAS ( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

4(2.53(207))

Since there are no equations in the parentheses, or exponents, we skip these, and head straight for multiplication:

4(523.7)

Then, do multiplication again:

2094.8

So that means, 4(2.53(207)) = 2094.8

I assume the brackets mean parentheses, since the absolute value of 523.7 does not mean anything in this equation.
