You will encounter word problems.
It will help you to make a chart of words and the algebra expressions that they represent.
For example,
the sum of a and b a + b
the difference of a and b a - b
the product of a and b a * b
the ratio of a to b a / b
is =
a is more than b >
a is twice b a = 2 * b
Add to this chart every day.
When multiplying two factors, an expression may leave out the "*" or "•".
Also, the words say "number and 12" which is x*12, but expressions (terms) in algebra put digits before variables, so it is written 12x.
