Instructions

Please enter a math expression below. Guess the first step before you click on the button. Then read the answer. Keep going until the problem is solved. Note: To perform pure integer operations, none of the numbers entered should include decimal points (i.e. ".").

Examples of integer math expressions follow:

4 + 5

.... which equals 9

**2*7 + (10/-5) + 5^2**

.... which equals exactly 37
(truncations^* possible with / and ^)

^* IMPORTANT NOTE: When performing integer math, division (/) and exponentiation (^) may yield somewhat unexpected results. Divisions will truncate to nearest integer (e.g. 9/5 = 1.8 which truncates to 1.) Negative exponents will produce a 0 result (e.g. 2^-2 = 1/(2^2) = 1/4 which truncates to zero (0).) This is intended for educational purposes only and is limited in the size and precision of numbers it can handle.

*27 + (10/-5) + 5^2**	.... which equals exactly 37 (truncations^* possible with / and ^)
