If you need to add or subtract two fractions that have the same denominator - simply add or subtract their numerators - like this: 3/4+1/4=4/4 or 1 - If the numbers in the denominators are different - this opertation will invovle a couple of extra s
Make sure that the bases are the same. To multiply - add the exponents and multiply the coefficients - and to divide - subtract the exponents and divide the coefficients - 3x^25x^3=15x^5 and 15x^6/3x^2=5x^4
When you see an answer choice that goes beyong the realm of the argument - you can consider it and eliminate it
