How Do You Square a Number?

How Do You Square A Number?

Summary

  1. Multiplying a number by itself is the definition of "squaring a number"
  2. Let's square the integer "2"
  3. The 2 shows us that the 2, 6, and 2.5 are being squared
  4. When you square an integer, you get a perfect square
  5. So 4 is a perfect square
  6. Let's square the integer "6"
  7. 36 is a perfect square because it's 6•6, or 6 squared
  8. Let's square the number "2.5"
  9. Notice that 2.5 is NOT an integer
  10. 2.5 squared is the same thing as 2.5•2.5, which is 6.25

Notes

    1. Squaring a number is the same as raising that number to the second power
