ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.
It is the longest side in a right-angled triangle. You can find it by squaring and adding together the two shorter sides and when you get the answer, find the square root of the number.
To add polynomials , simply combine similar terms. Combine similar terms get the sum of the numerical coefficients and affix the same literal coefficient .
In all there are [at least] 24 trigonometric functions and ratios. Half of these are circular and the other half are hyperbolic. Sine and Cosine are basic trigonometric funtions, abbreviated as sin and cos. Tangent is the third basic ratio defined as Sin/Cos. For each of these three, there is a corresponding reciprocal function: Sine -> Cosecant (cosec or csc) Cosine -> Secant (sec) Tangent -> Cotangent (cot). Each of the above six has an inverse function, defined on an appropriate domain. They all are named by adding the prefix "arc", for example arcsin, which is usually written as sin-1. The above are the circular functions. Each one of them has a corresponding hyperbolic equivalent. These are named by adding the suffix, "h", thus cosh, sech, arccosh [= cosh-1], etc.
Try and show this as well as you can: Think of a wheel, or whatever that is cylinder-shaped. One point on the wheel's base is our aim of attention. If you look at the wheel from the side, and roll it at a constant speed, one point on the wheel makes a sine curve. You could illustrate by adding something that leaves a trail to a cylinder. Like gluing a piece of chalk on a scroll of tape. Then roll the scroll next to a blackboard, and the result should be a sine curve, where the amplitude is the same as the radius of the scroll.
When adding and subtracting radicals, you can only combine radicals with the same index and radicand (the number inside the radical). Here are some examples:
Subtracting a fraction is the same as adding its negative.

adding
Adding and subtracting polynomials is simply the adding and subtracting of their like terms.
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
What is the definition of Adding and Subtracting Like Fractions
adding and subtracting integers is when you add and minus 2 numbers
only when adding and subtracting
adding
Subtracting a negative is the same as adding the equivalent positive. For example, subtracting minus 10 is the same as adding 10.
Anything having to do with adding or subtracting unlike fractions.
