Given a number square it then subtract the sum of twice the number and 4 The result is zero Find the number?
There aren't any whole numbers that satisfy this.
How do you do mean medium mode and range?
To find mean: add all the numbers and divide by the amount of numbers. To find medium: put the numbers in order and find the middle value. If there are two, add them and divide by two. To find mode: find the number that appears most often. To find range: subtract the lowest number from the highest number.

To find biggest of three number?
Let the numbers be A,B and C and assume that A ≠ B ≠ C 1) Subtract B from A. If the result is a positive number then A > B otherwise B > A. 2) Subtract the greater of A and B from C. If the result is a positive number then C is the largest number otherwise the subtrahend (either A or B) is the largest number.
