Okay =) So she taught us that 30+10 is equal to 40, that 2p=100, therefore p=100/2, so p=50, how to plot points in order to draw a straight-line graph and how to substitute numbers into a linear equation step by step. And, and she said the lecture was an intensive one and it's ok if we don't get it now. Oh yeah =/ Without challenges, one will never try,
Without setbacks, one will never triumph,
Without losses, one will never appreciate.
