Question about Texas Instruments TI-83 Plus Silver Edition Calculator

My calculator squares negative numbers incorrectly. When I enter "-2" and square it, the calcular answers "-4." Is there any way to fix this without having to reset my calculator?

When you type -2 imagine your calculator doing the equation: -1 x 2. The - sign actually stands for a -1 so when you do -2 squared your calculator is simply following order of operations. It first squares the 2 making it 4, then it multiplies the negative making it -4. In order to get around this you must use parenthese. (-2)^2.

Hope this helped

take you sales for the last year and put it into a calculator, then press plus + and then 6 and then the per cent key %

Or

Take your sales from last year, multiply by 6 and then divide by 100. That is the amount you will increase. Add it to last years sales.

118.3 cu3 = 24.0985 cu2 (square feet) 24.0985 X 12inches = 289.182 square inches.

It might be 118.3 cu3 X 12 inches = 1419.6 cubic inches

Not quite sure what you needed.

volume is calculated by finding the area multiplied by the length or height . That is Pi X radius squared X length

example --tube 6"dia 12"long what is the volume?

Example 3.1417 X radius 3" Squared =3.1417X9sq " = 28.2740sq" X length 12" =338.688 cubic"

If you want the volume of an engine cylinder , it is the same formula and the length is the stroke of the piston ( distance from TDC to BDC )

Circumference of a Circle: 2 x pi x radius - OR - pi x diameter,

or if you need some sphere calculations?

Sphere Surface Area: 4 X pi X radius squared OR

pi X diameter squared Sphere Volume: 4/3 X pi X radius cubed OR

( pi X diameter cubed ) / 6

By the way.......... "pi" = 3.1415926536
