How Do You Square A Number?
Summary
- Multiplying a number by itself is the definition of "squaring a number"
- Let's square the integer "2"
- The 2 shows us that the 2, 6, and 2.5 are being squared
- When you square an integer, you get a perfect square
- So 4 is a perfect square
- Let's square the integer "6"
- 36 is a perfect square because it's 6•6, or 6 squared
- Let's square the number "2.5"
- Notice that 2.5 is NOT an integer
- 2.5 squared is the same thing as 2.5•2.5, which is 6.25
