Should I learn a new language or learn calculus I?

I know some of the Classical Nahuatl language, which really interests me, but I I also want to learn calculus, which also interests me. The reason I ask this is because it can only get two of the following books Nahuatl as http://www.amazon.com/Nahuatl-Written-Lessons-Copious-Examples/dp/0804744580/ref = pd_sim_b_5 Grammar of the Mexican Language, with an explanation of adverbs or calculation http://www.amazon.com/Grammar-Mexican-Language-Explanation-Adverbs/dp/0804742812/ref=sr_1_1?ie=UTF8&qid=1231823128&sr=8-1 http://www.amazon. com/Calculus-Michael-Spivak/dp/0914098918/ref = pd_bxgy_b_img_b Answer book for CALCULS http://www.amazon.com/Combined-Answer-Calculus-Fourth-Editions/dp/0914098926/ref=pd_cp_b_1?pf_rd_p=413864201&pf_rd_s=center-41&pf_rd_t=201&pf_rd_i=0914098918&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1ZGG179MNQBGXRTNY73H

Calculation seems funny, but honestly, unless you are going to be a physicist, then you do not.
