The spelling out of number in Spanish applied for the exercise is actually simple, you must know the number since 0 to 100 and remembering that, regularly, <em>the correct form to spell them is the first solo, and the other numbers in pairs,</em> <u>this is not an obligation, because sometimes the people prefer saying the numbers one on one for evading mistakes with numbers that sound similar</u> (for example 60 that is "sesenta" and 70 that is "setenta"), but the form in the exercise is the regularly used in Spanish.
