Translate the Words Into Math
Word problems are not a different kind of math. They are just regular math wearing a disguise.
The best way to figure out ANY word problem is to translate, phrase by phrase, before you solve anything.
A quick dictionary: "is" means equals, "of" means multiply, "per" or "for each" means a rate, and "more than" means add in most situations, unless you are talking about a percentage more than.
So "Nadia earns 15 dollars per hour" becomes 15h, and "8 less than twice a number" becomes 2n minus 8.
Key difference, especially on the SAT: "50 percent of 100" means something different than "50 percent more than 100." Make sure you know this distinction!
Write down what your variable stands for in plain words first. Most word problem misses come from solving the right equation for the wrong thing.
Coach's Move
Take one word problem and translate it line by line into symbols before solving. Define every variable in writing.
Numbers don't lie. Neither does practice.
