Comparing Expressions We compare expressions using < less than > greater than = equal to How do we compare them? It's pretty simple: First, you figure out the value of each expression (what answer each one gives you) Then, you just compare those values using =, <, or > Let’s do some examples Is 10 + 2 bigger or smaller than 7 + 1? 10 + 2 has a value of 12 7 + 1 has a value of 8 Since 12 is greater than 8, we write: 10 + 2 > 7 + 1. Which is bigger when you compare 13 − 2 to 4 × 3? 13 − 2 has a value of 11. 4 × 3 has a value of 12. Since 11 is less than 12, we write: 13 − 2 < 4 × 3 Let’s do some questions
