How do i make fraction with a number next to it on the left side

A mixed number.

Try using an improper fraction?

type in your improper fraction numerator first

click the 1/x button

delete the default number inside the parentheses and type in your denominator

Say you want to do \(3\frac{1}{4}-1\frac{4}{6}\)

put it in as

(3+1/4)-(1+4/6)=

(3+1/4)-(1+4/6)= = 1.5833333333333333

The calc also tells you that it is \(\frac{19}{12}\)

But you have to be able to change that to \(1\frac{7}{12}\)
