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.

Respuesta :

Well, we just need to perform the operations:

  • Multiplication: [tex] 1\cdot 2 \cdot 3 \cdot 4 \cdot 5 = 120 [/tex]
  • Subtraction: [tex] 1-2-3-4-5 = -13 [/tex]
  • Addition: [tex] 1+2+3+4+5 = 15 [/tex]
  • Division: [tex] 1 \div 2 \div 3 \div 4 \div 5 = \frac{1}{120} [/tex]

So, if you add all the numbers together you get

[tex] 120-13+15+\dfrac{1}{120} = 122 + \dfrac{1}{120} [/tex]

Or, if you prefer,

[tex] \dfrac{1681}{120} [/tex]
