Excel averages

in BTT class today i learned how to find my class averages in excel it was kinda hard and tricky at first but then i got kinda easier. we played with formula in excel we leraned that instead of asking questions you can find out your own formula if you wanna know what your average is. its really easy tho just click the boxes you wanna subtract add multiply or divide and youll get your anwer then just drag the box down and it will do the samre for everything. i leraned alot today and its really good for someone to learn all this stuff because your olny grade 9 and if you know all this now its better for you until grade 12 because you would know how to use excel more than anyone else. thts the good thing about business you learn everything that another person might not have the chance to learn from but if you have this class use your time wisley.
