First, multiply seven times three. The answer to that is 21. Then add four for the final answer, which is 25.
1 7/12 (one and seven-twelfths)
thirty-three

3 + (-4) = 3 - 4 = -1
four to the fifteenth add the third to the second... and multiply it by the three answer: 1073741824
It is four and one half.
At least four, but it can be more. If the base is a triangle (three sides) add the base and you get four. if the base is a quadrilateral (four sides), add the base and you get five. However many sides the base has, add one.
