    Number Grids My task is to find an algebraic rule for different sized squares in a set sized number grid. To do this I will establish my algebraic rule by creating a 10×10 square and marking out 3 different sized squares inside this square. I will then work out the rules for these individual squares and combine them to create my overall rule. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

I then used the formula lx4 to find the areas of the four sides, for example: 16x4=64cm I then calculated the volume of the tray. The calculations I used to find out the volume of the tray were: 14x14=256cm = 256x2=512cm The formula I used to calculate

    there are 3 premolars and 2 or 3 molars. This results in a dental formula of 2.1.3.2 or 2.1.3.3. In contrast, all of the catarrhines have 2 premolars and 3 molars, making a dental formula of 2.1.2.3. The chimpanzee shown below is an Old World anthropoid species and, therefore, has a catarrhine dental formula. Catarrhine 2.1.2.3 dental formula (common chimpanzee) All Old World monkeys, apes, and humans share this 2.1.2.3 dental formula. This not only sets us apart from New World monkeys and prosimians
