Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

Anything multiplied by 0.5 is the same as halving it. In this case, half of 53 is 26.5.
Sputnik was the first satellite to orbit the Earth. It was Russian and transmitted a radio signal. It is possible that a earlier satellite could be in orbit, without any communications this would be the same as a cannon shell etc. So long as an object can reach orbit it will constantly drop towards the planet and because the planet is round the object will rotate around being pulled by gravity

What is 2y-x equals 0 y equals 3x-5?
If this is a system you have Y expressed in terms of X.
2(3X - 5) - X = 0
6X - 10 - X = 0
5X = 10
X = 2
--------------find Y
Y = 3(2) - 5
Y = 6 - 5
Y = 1
----------------check in first equation
2(1) - 2 = 0
2 - 2 = 0
0 = 0
both check and system is consistent
It could be a mathematical formula. If you equate it to a value, you can solve for X, if you want. For example if (X+5)/8 = 20, then X = 8x20-5, which equals 155. Now, if you mean X+5/8, then if you set it equal to 20 you get X = 20-5/8, which equals 19 3/8 or 19.375. All by itself though, X plus 5 over 8 could be anything. Or nothing.
How many cubic meters in 787 square meter by 10 centimeters?
787 sq m * 10 cm = 787 sq m * 0.01 m = 7.87 cubic metres.
1.5x10 to the 2 power plus 2.0x10 to the 3?
1.5 x 102 =1.5 x 100 = 150
2.0 x 103 = 2.0 x 1000 = 2000
So your answer is 2150
Which subsets of numbers cannot be irrational?
Integers, rationals. Also all subsets of these sets eg all even numbers, all integers divided by 3.
What is the value of 8x - 6 when x is equal to -1?
given x=-1
8x-6
Putting value of x=-1,
8 (-1) -6
= -8-6
=-14
so answer is -14
Matrices (Plural of matrix) are used in calculus and algebra in particular linear algebra. Matrices are rectangular arrays of numbers.
As an example, you must subtract. Subtract the numbers in the matching positions (top left - top left, middle-middle, etc)
[2 4] [3 5] = [5 9]
[5 1]+ [2 4] [7 5]

How would you solve x-1 equals 4?
By adding one to each side of the equation. The general approach to this kind of problems is to "isolate" the variable (in this case, "x") on one side of the equation, getting rid of anything else. However, you must always do the same thing on both sides of the equation, otherwise, you will get wrong results.
