Tiara,
In a word problem,
when ever it refers to a number you can call it X
sum refers to addition +
so the sum of a number and six is written as X + 6
if I need to know what 3 times that would be it is written 3( X + 6 )
If this was helpful and you would like further tutoring please contact me through WyzAnt
