What did Factor mean in Algebra?
In algebra, a factor means one of the numbers that divide a number without leaving a remainder, making it a whole number. It is one of the most important concepts in mathematics and is used frequently throughout the curriculum.

It’s a good idea to teach your students the different ways in which factors are calculated, and this teaching wiki contains a comprehensive explanation of all the methods. You can also use the Find the Factors Worksheet and this colorful Factors and Multiples PowerPoint Quiz to support your teaching of factoring.
A term is a single mathematical expression, which can be a number, a variable, or several constants multiplied together. Terms are usually separated by addition or subtraction operations, but they can be separated by brackets, e.g. x2 + 3x = 6(2 -x3).
There are two main types of terms in algebra: a coefficient, which is a number, and a constant, which is not multiplied by a variable. The coefficient is the lone number that comes before the variable in a polynomial. For example, x2 is the coefficient of x, while 8 is the constant in the polynomial x2 + 6x+ 8.
What Does Coefficient Mean?
In algebra, a coefficient is a number that is multiplied by a variable. For example, the coefficient of x2 is 1 because x2 is multiplied by 1.
What Does Constant Mean?
In maths, a constant is a number that remains the same throughout an equation. For example, the constant in 12x + 19y -1 is -1, even though 12x and 19y change every time you add them to each other.
What Does Variance Mean?
In maths and science, variance is a statistical measurement that measures how far each member of a set is from the mean. It is a useful tool for measuring differences among sets of data.
What Does Linear Scale Factor Mean?
The linear scale factor is the ratio of two corresponding side lengths for similar figures. It is a useful tool for solving geometric problems, such as the problem of finding the missing side lengths in a figure or calculating the scale factor between two symmetrical shapes.
It’s a good practice to make sure that your children have a firm understanding of linear scale factors before they move on to the next topic, as it will help them to recognize it when they encounter it later in their studies.
What Does Prime Number Mean?
In algebra, a prime number is a number that cannot be divided exactly except by itself or by its factor. It is a useful concept to understand, and this Teaching Wiki includes information about the different ways in which prime numbers are calculated.
What Does and > Mean?
In maths, and > are both mathematical symbols that are used to show ‘less than or equal to’ or ‘greater than’. Often they are used in conjunction with another symbol, such as ‘+’ or ‘-‘, to indicate confidence intervals around a number, for example, 5 +- 2 could in practice be any number from 3 to 7.
It’s a good idea to start with the most simple concepts first and then progress to more advanced topics so that your children can build their confidence when they encounter them later on in their studies. You may want to use the Find the Factors Worksheet to help your children to recognize factor pairs before they move on to more complex equations and sums, or the colorful Factors and Multiples PowerPoint Quiz at the end of a topic to round off their learning.
