🧮 How to Form Two-Digit Numbers

Pattern: [Tens] + [Ones]

21 = Twenty + One = Twenty-one

35 = Thirty + Five = Thirty-five

67 = Sixty + Seven = Sixty-seven

99 = Ninety + Nine = Ninety-nine

Use a Hyphen (-) Between!

✅ Twenty-three

✅ Forty-eight

✅ Seventy-six

❌ Twentythree (no hyphen = wrong!)

⚠️ Watch Out!

FORTY ≠ FOURTY

40 = "Forty" (no U!)

-TY vs -TEEN

30 = ThirTY, 13 = ThirTEEN
