8 = 23. Here are the first few integers:
DECIMAL: OCTAL : BINARY (Isn't there a way to make a table here?)
Each system has the corresponding number of different digits -- ten : eight : two -- so when the count first reaches a new power of that number (bolded above: ten, [a hundred, a thousand...] : eight, [sixty-four, five-hundred-twelve...] : two, four, eight, sixteen, [thirty-two...] ) you need to add another place, writing a 1 and as many zeroes as the power.

area of triangle e= 1/2 X base Xheight 32 = 1/2 X base X 8 base =32/4 =8 inches
1/2 base x height so 1/2 B x 16 = 64. 1/2 of 16 is 8 and 64/8 = 8 so the base is 8 feet
Pythagorean theorem. a^2 + b^2 = c^2. Base divide by 2 = 6 which is the base for each of half of this triangle. Thus 6^2 + 8^2 = c^2. C= 10. The Length of each of the two legs is 10.
area = 1/2*base*perpendicular height =1/2*21*8 =84 square inches
462 base 8 - 177 base 8 = 263 base 8 , (that's 179 in base 10) I used the octal feature on the windows calculator.
