Buford o kwala ditšheke di le dintsi ngwaga le ngwaga.  Gangwe ka kgwedi o kwala tšheke go duela motlakase.  Gape o kwala tšheke kgwedi le kgwedi ya gase.  Gabedi ka kgwedi o kwala tšheke ya kereke. Mme kotara ngwaga le ngwaga, o kwala tšheke ya tirelo ya disenyi le ya bojang.  Ke ditšheke di le kae tse Buford a di kwalang ka ngwaga?

An air conditioner cools a room 2 degrees an hour on low and 3 degrees an hour on high. The room will warm up at 2 degrees an hour with no air conditioner running. The air conditioner ran on low for 3 hours, then it was turned up to high for 4 hours. Afterward, it was turned off for 2 hours. How many degrees lower than the starting temperature was the final temperature?
Gangwe ka kgwedi o kwala tšheke go duela motlakase, kgotsa 1*12=<<1*12=12>>12 ditšheke ngwaga le ngwaga.
Gape o kwala tšheke kgwedi le kgwedi ya gase, kgotsa 1*12=12 ditšheke ngwaga le ngwaga. 
Gabedi ka kgwedi o kwala tšheke ya kereke, kgotsa 2*12=24 ditšheke ngwaga le ngwaga.
Kotara ngwaga le ngwaga, o kwala tšheke ya tirelo ya disenyi le ya bojang, kgotsa 1*4=<<1*4=4>>4 ditšheke ngwaga le ngwaga.
Ka kakaretso, Buford o kwala 12+12+24+4=<<12+12+24+4=52>>52 ditšheke ngwaga le ngwaga.

The air conditioner ran for 3 hours on low, so the temperature dropped 2 * 3 = <<3*2=6>>6 degrees.
It then ran for 4 hours on high, so the temperature dropped another 3 * 4 = <<3*4=12>>12 degrees.
It was then turned off for 2 hours, so the temperature rose 2 * 2 = <<2*2=4>>4 degrees.
Thus, the final temperature was 6 + 12 - 4 = <<6+12-4=14>>14 degrees lower than the starting temperature.
