Lecture Notes: Numbers 30-100 and Course Updates
Numbers 30 to 100
30 to 39
30 is referred to as "treinta" in Spanish.
To add a number to 30, use "treinta y [number]" (e.g., treinta y uno).
40 to 49
40: cuarenta, e.g., cuarenta y uno.
50 to 59
50: cincuenta, e.g., cincuenta y dos.
60 to 69
60: sesenta, e.g., sesenta y siete.
70 to 79
70: setenta, e.g., setenta y tres.
Reminder: Six has an 'S', Seven has a 'T'.
80 to 89
80: ochenta, e.g., ochenta y cuatro.
90 to 99
90: noventa, e.g., noventa y cinco.
100 and Beyond
100 is "cien". For numbers over 100, use "ciento" (e.g., 101 is ciento uno).
Practice Problems
Math exercises:
15 + 15 = 30 → quince más quince son treinta.
80 + 17 = 97 → ochenta más diecisiete son noventa y siete.
77 - 22 = 55 → setenta y siete menos veintidós son cincuenta y cinco.
60 - 19 = 41 → sesenta menos diecinueve son cuarenta y uno.
59 + 6 = 66 → cincuenta y nueve más seis son sesenta y seis.
100 - 25 = 75 → ciento menos veinticinco son setenta y cinco.
22 + 24 = 46 → veintidós más veinticuatro son cuarenta y seis.
16 + 36 = 52 → dieciséis más treinta y seis son cincuenta y dos.
99 - 10 = 89 → noventa y nueve menos diez son ochenta y nueve.
73 + 27 = 100 → setenta y tres más veintisiete son cien.
