Adding & Subtracting Fractions

[Gaby]

a-6 + 4-a
15 10
the ten is supposed to be under the second term

What I usually do is multiply each side by the denominator (fifteen) to start, but this looks like a different problem...I'm sorry, I thought I could help!

Multiply the first by 2/2 and the second by 3/3.

PS If you click twice on the C(ode) button then type between the boxes it will look like

   a-6   4-a
   --- + ---
    15    10

Or you can type

(a-6)/15 + (4-a)/10
