Mathematical proof

What you'll learn

1. 1

   A proof is a logical chain of reasoning that shows a statement must be true, like a detective solving a case. 🕵️

2. 2

   Drag the steps into the correct order to prove that the sum of two even numbers is always even. 🧮

3. 3

   Let's prove that the sum of two odd numbers is even. 📝

4. 4

   What do we call a statement we assume is true at the start of a proof?

5. 5

   Prove that the product of an even number and an odd number is always even. 🧪

6. 6

   Here's another: prove that if n is odd, then n² is odd. 📐

7. 7

   Which of these is a valid proof that the sum of two even numbers is even?
