It means “greater than” … you could reverse the math equation to 12 < 5x-9 and it would be read as "less than". An easy way to remember is to think of the symbol as an alligator’s mouth – the alligator always wants to eat the bigger thing! The Arithmetic Mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: • add up all the numbers, • then divide by how many numbers there are. Example: what is the mean of 2, 7 and 9? Add the numbers: 2 + 7 + 9 = 18 Divide by how many numbers (i.e. we added 3 numbers): 18 ÷ 3 = 6 So the mean is 6Some examples of mathematical expressions include “mx + y,” “5 /a,” “20” and “6 – 4.” Mathematical expressions are groups of variables, constants and operators that represent values.Mean: The "average" number; found by adding all data points and dividing by the number of data points. Example: The mean of 4 , 1 , and 7 is ( 4 + 1 + 7) / 3 = 12 / 3 = 4 . Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). Jan 6, 2023 · In math, the letter “i” is called the imaginary unit. It is used to represent the value of the square root of -1, which cannot be represented as a real number. This means that “i” is a purely imaginary number, or a number that exists only in the complex plane. Complex numbers are numbers that have both a real and an imaginary component.
