Uh... To multiply, you must do repeated addition.
ab = a + a + a + ... + a
b times
TO find the area of the triangle, we use this formula

10 + 9 = 9 + 10
10 + 9 = 19
9 + 10 = 19

Help me in Math Olympiad!!!
The questions use the current year!
Given that xyz = 2016 and x, y and z are positive integers such that x < y < z, how many possible triples are there?
When I try using a calculator, my calculator calculates only ranges of:
± 1 × 10-99 ≤ x < 1100 or 0.
The maximum factorial used for my calculator is:
69 !
(-n)(n) = -n * n
= - n2
The calculator will show up results like:
x × 10y or some errors that go above 9.999999999999999 × 1099
Also calculators are NOT allowed in the contest of Math Olympiad.
3 / 5000 = (3 ÷ 50) / (5000 ÷ 50)
= 0.06 / 100
= 0.06 %

negative 1440 feet
We use negative when the number is below 0.
But we use positive when above 0.
