📚 Topic Summary
Algebraic expressions are like secret codes in math! They use letters (called variables) to represent unknown numbers. Word problems turn real-life situations into these codes. To solve them, you need to figure out what the letters stand for and then use math to find their values.
This worksheet will give you some practice translating word problems into algebraic expressions and solving them. Get ready to unlock some math mysteries!
