Hi, my name is erika and i would like to ask you a mathematical question on Simplifying Variable Expressions. I am only in the 7th grade and in prealgebra. The question is 2(n4)+3. Thanks for your time!! 

Hi Erika, The simplification is possible because of the way that the multiplication by 2 distributes across the factor (n4). For example, if n were 7 then you could calculate 2(n  4) as Your expression is 2(n  4) + 3 which simplifies to Penny
