Example :



The exponent is 3 in this case and is positive meaning the zeros will follow after the 5 in 4.5 and not before that like this,



If it was negative then the zeros would follow before the 4 in 4.5 like this,





The picture shows how it is done!!

Just do the loops around the number and put and egg inside of it like a cup.

That's all!!

Exponents :



Or 9^2 is titled 9 to the power of 2.

You do NOT do this...



You do,
