Math and Arithmetic
Math is the study of abstractions. Math allows us to isolate one or a few features such as the number, shape or direction of some kind of object. Then we can study what can be learned about the behavior of those features while ignoring everything else about the object.

What instrument measures liquid volume or capacity?
- 1 answer
There are manu instruments capable of measuring liquid volume:
- In laboratories, typical volume measuring devices include graduated cylinders and beakers, and measuring/volumetric flasks. For home use, the equivalents are measuring cups and spoons.
- If you wanted to put a precise volume of a liquid into a jar you might use a burette (a graduated glass tube with a tap at the bottom that you can let exactly the right amount through).
- Or you could use a pipette (a glass tube with a bulge in the middle and a line on the neck. You suck liquid up until it reaches the line and depending on what the size of the pipette is you have an exact quantity.
- A measuring jug or normal scales works millilitres and grams are the same.
- Mathematically, if you know the dimensions of the container of the liquid you can find it's volume and calculate the volume.
- Or you could find the volume indirectly: for example by measuring the time it takes to fill at a known flow rate, or by measuring the mass of liquid and using the density.
They use a graduated cylinder.

What is the anti-derivative of 5x?
- 1 answer
∫ xⁿ dx = xn + 1/(n + 1) + c where n is any constant except 0 and -1.
Apply that rule to get:
∫ 5x dx
= 5 ∫ x dx [Factor out the constant]
= 5 ∫ x1 dx [Make note of the exponent for x]
= 5x1 + 1/(1 + 1) + c
= (5/2)x2 + c
