One of the biggest problems is that there are so many different concepts and equations in algebra and in order to be successful you have to understand the entirety of it or you will not be able to figure out which procedure to use. You learned the order of operations years ago and that is one key tool for algebra. This tool allows you to understand which process happens first and so on. PEMDAS is a very valuable tool.
Addition is an operation in which one number is added to another number. When adding a series of numbers, there are some strategies that help simplify the addition process. One thing to remember is to group numbers to make tens. For example, when adding 2 + 7 + 8, you can add the 2 and the eight first to get ten, and then add the seven to get 17. Some teachers call these groups of numbers that add to ten, "friendly tens," since they make adding easier for the student.
If the two values being subtracted are mixed fractions, it is often easier to turn them into improper fractions to perform the subtraction. This avoids any kind regrouping or borrowing from the minuend fraction if the numerator in the subtrahend is larger.
When adding fractions without a common denominator, it is necessary to find a common denominator before adding the numerators. Find two equivalent fractions by determining the least common multiple of the two denominators and using that as the denominator for both fractions.
