I have 3 years of experience in this field

8! = 40320 and 3! = 6 so 8!-3! = 40320 - 6 = 40314 thus answer is 40314

Solution to Maths

It's 40314. The sign '!' after the number is a factorial sign. It calculates the product of integer and all integers below it. So, for example 4! = 4x3x2x1 = 24. 8! = 8x7x6x5x4x3x2x1 = 40320 3! = 3x2x1 = 6 Thus 8! - 3! = 40314.
