this week in math, i learned about the different problems like age problem. i really had a hard time in the test this Friday. all those problems really took me some time to solve. i used crammer's rule on number 4 and i had a little ease on that number. using the crammer's rule helped me out on that one! but i'm not so sure about my answer though!
well...that's all!
