* - this symbol is commonly used while typing expressions on a computer The only difference between them is the “location” of use. * or × or ⋅ MultiplicationĪll signs that express multiplication of numbers are equal. For example, 4☑ refers to 3 and 5 at the same time. Sometimes we do not need to find the only number that will be a solution, but the requirement is to identify the range of numbers. In this case, we deal with an interval around one particular number. There are expressions where two symbols can go together. Another case where we use a subtraction symbol is negative numbers (-2), as we have already mentioned. For instance, a non-verbal equivalent for “five minus two” is 5-2. The subtraction symbol - a short horizontal line - stands for the expressions where we subtract one number from another. These two crossed lines, plus, can also be used while speaking of positive (+2) or negative numbers (however, plus is not always necessary there). If we want to add two numbers together, we say “three plus four” and write 3+4. The addition symbol is used in mathematical expressions where we have to add one number to another. They refer to the various solutions of the equations, for example. They look the same as the previous ones but with the additional line underneath ( ≥ or ≤). When learning algebra, you can come across the symbols like “less than or equal to” and “greater than or equal to”. Let’s look at the examples to make it clearer: to state that “five is greater than three”, we write 5>3 to state that “one is less than six”, we write 12+2. These symbols help us to make comparisons between numbers or expressions. The question is, what side to choose? It is pretty simple - the large opening points to the bigger value, the small tip closes next to the lower value. We should rotate the letter “v” by 90 degrees to the left or to the right to write them. If we want to be more precise in terms of inequality, we use Less Than () symbols. This symbol, like the previous one, is not widely used, although sometimes you can come across it. For instance, when we state that some expression is not correct: 2+2≠5. For this purpose, we use crossed parallel lines ( ≠). Sometimes two parts are strictly unequal. Just keep in mind that in some cases, it is acceptable. But be careful: ьathematics is a very precise science, so we should avoid using inaccurate expressions. For example, “two plus two equals four” we can write as “ 2+2=4“ or with expressions: 2+2=3+1.īut what if two sides are not equal? Can we show it with a maths symbol, as well? Sure we do! Firstly, to show that two parts are approximately equal, we use two wavy lines ( ≈). We can use this symbol to show the same value of the sides or demonstrate the result of some calculations. If we see two parallel lines between two numbers or expressions, it means that one component equals another. Let’s discover what mathematical symbols we can use! = Equals

In other words, we can call math symbols the unique mathematical language which enables us to replace some sophisticated verbal constructions with commonly used pictograms. Also, they help us to save space while solving mathematical problems. Math symbols surround us every day, but basically, they are used in mathematics to refer to a particular object or action.
