The last time you posted you had: 34/4+5+2.3+12/3+1 Now you tell us it's 36/4+5+2.3+12/3+1=6 It looks as though you have trouble getting it exact. 34 was changed to 36 and =6 was added on the right. Is the 2.3 "two and three tenths"? Is that a decimal between the 2 and the 3? Or is the dot between the 2 and 3 supposed to be multiplication, like this: 36/4+5+2∙3+12/3+1=6 If you mean the decimal 2.3, it looks like it'll be impossible to get a whole number like 6 as an answer. The decimal 2.3 is going to make the left side a decimal no matter what you do, and it will never come out to 6. Edwin.
