Make 37

This week we have been learning how to make 37 out of 10 numbers using 1, 3, 5 and 7, but I found out that it's impossible to make 37 out of those numbers because odd + odd =E and all the numbers we use are all odd. So they will equal even numbers. The easy part is to make 37 out of 9 and 11 numbers. The hard part is to make 37 out of 10 numbers. I can finish this equation by using 11 and 9 numbers but not 10.
Here is 3 examples

  • 7+7+7+7+3+1+1+1+1+1+1=37
  • 1+7+1+7+1+7+1+7+1+3+1=37
  • 1+1+1+7+5+5+7+7+3=37
