then we get \[2\infty /\infty+5\]

the +5 is going to be meaning less next to infinity so we throw it away

so we are left with \[2\infty/\infty \]
then we cancle the infinity cause it is on bith the top and bottom we are left with 2

try to think of infinity as a large number not a consept, how big is 5 compared to 1,000,000?

it is insignifigant, so we just throw it away, the 2 is actualy saying infinity+infinity so that is significant

so think of it as simplifying the fraction 2,000,000 / 1,000,000
