30
1+30=31 and 1x30=30
I was able to get the number 30 by adding 4 odd numbers 3 + 7 + 5 + 15 = 30 But i can't add 5 odd numbers to get 30
Depending on the restrictions applied to the problem, there are an infinite number of solutions. Whether you may use fractions are not, if you are restricted to the natural numbers or if all the real numbers are included, if you may use negative numbers. The easiest solution would be 30, 0, 0, 0. Another simple solution would be to have all the numbers be equal to themselves. If we represent x as one of the numbers and all numbers are equal in between themselves, we have that x + x + x + x = 30 or 4x = 30 From there you must divide both sides of the equal sign by 4 (just 4) so that x = 30/4 From there it's simple fraction reduction (30 and 4 are divisible by 2) so x = 15/2 Then, if you are allowed decimals, you can transform fraction x = 7.5
