  3. Irrational Numbers Decimals Non-Perfect Squares

  4. Irrational Numbers Decimals • Never Terminates • Never Repeats • Goes on Forever • 0.4567… • -2.8191… • -0.3322… • 5.2468…

  5. Irrational Numbers Non-Perfect Squares • No whole number times itself equals what’s under the radical (use DAD)

  6. Irrational Numbers • Estimated to be 3.14 • Actually equals 3.141592… • Never terminates, Never repeats, Never ends
