If you have an even number of values in a given set, and you are asked to find the median, find the mean of the two middle values, and present that as your answer.
Example:
4, 9, 13, 30, 44, 50, 71, 76, 92, 152
Find the two middle numbers
4, 9, 13, 30, 44, 50, 71, 76, 92, 152
Find the arithmetic mean (average) of the two numbers
(44+50)/2=47
Quadratic equation
The sign changes if you multiply/divide by a negative number. It stays the same if you add/subtract by a negative number.

You can make lots of equations that have the solution 21. Here is one:x = 21If you think that is too trivial, add, subtract, multiply, or divide the same number to or from both sides.
The size of the quantities involved doesn't matter. As long as you add or subtract (or divide or multiply) the same number to or from both sides of the equation, then the two sides remain equal.

1. Pick a number 2. Multiply by two 3. Add 12 4. Subtract 8 5. Halve it (Divide by 2) 6. Subtract original number ... HOPE THIS HELPSSS <3333

subtract
The difference is that instead of the sign "=", an inequality sign, for example "<" (less-than) is used. For solving inequalities, you can add, subtract, multiply or divide both sides by the same number, similar to an equation; however, if you multiply or divide by a negative number, the direction of the inequality changes. For example, "<" becomes ">".
Subtract that number from. Your welcome dumb
Divide the number by 5 and subtract the answer from the original number...

94 i think
Divide the new number by the original number, subtract '1', and multiply by 100.
