The function of% in the ordinary calculator of windows
For example, 50 + 25% = 50 + 12.5 = 62.5, 4 + 2% = 4 + 0.08 = 4.08; 25% = 0, 0.09% = 0
What is the solution


50 + 25% = 50 + 12.5 = 62.5 is equivalent to 25% of 50 + 50, 25% of 50 is 12.5
4 + 2% = 4 + 0.0. = 4.08 is equivalent to 2% of 4 + 4, 2% of 4 is 0.0.8
25% = 0 and 0.09% = 0 are equivalent to 25% of 0 and 0.09% of 0 are both 0
