Question

12345 what is the answer if you multiply 1x2x3x4x5 and do the same with subtraction, addition and devision, in that order. Then add the totals together.

Answer 1

Well, we just need to perform the operations:

• Multiplication:
  `1\cdot 2 \cdot 3 \cdot 4 \cdot 5 = 120`
• Subtraction:
  `1-2-3-4-5 = -13`
• Addition:
  `1+2+3+4+5 = 15`
• Division:
  `1 / 2 / 3 / 4 / 5 = (1)/(120)`

So, if you add all the numbers together you get

`120-13+15+(1)/(120) = 122 + (1)/(120)`

Or, if you prefer,

`(1681)/(120)`
