In mathematics, we tend to equate two items or expressions when we show the equality between the two expressions. The equal sign in math is a sign that shows the equality between two expressions. In simple words, the meaning of equal sign is that there is an equality between the values, or expressions written on both the sides. The symbol that repr...
Robert Recorde, a Welsh physician and mathematician, invented the equal sign (=) and also introduced the pre-existing plus sign (+) to English speakers in 1557.
An equation is a statement of equality between two mathematical expressions that contains variables and constants. In every equation, the expression given on the left-hand side (LHS) is equal to the expression given on the right-hand side (RHS). For example: 5+3=8 This means that the LHS is 5+3and it is equal to the RHS, which is 8. If we have an e...
The amount or quantity or length of any object is shown by measurement. For example, Oliver is given the task of measuring the length of a spoon. He uses a centimeter scale to measure its length. He finds out the distance between the start and the endpoint of the spoon. The length of the spoon =16cm. It means that the length of the spoon “is equal”...
Fractions tell us about the part of a whole. In fractions, the equal sign between two fractions represent that they are equivalent fractions or the fractions cover equal parts of a whole. For example: 15=210 means that 15 is equivalent to 210.
The equal sign with two lines means two expressions are equal. For example: a=4,b=12. On the other hand, the equal sign given with the three lines means two things are identical. It is similar to but not necessarily the same as an equal sign.
The equal sign with slash means that it is the unequal sign, i.e.,≠. It is used when two expressions are not equal. For example: 5≠8means that 5 is not equal to 8.
1. The product of two numbers a and b is exactly 12. How can you represent it mathematically? Solution: The given statement is “The product of two numbers a and b is exactly 12.” It can be represented mathematically using the equal sign. Therefore, ab =12is the required equation. 2. What is the value of y if 3y+7=28? Solution: 3y+7=28 3y=28−7 3y=21...
Generally, when there are \ (n\) numbers, the median will be the \ (\frac { (n + 1)} {2} th\) number. For example, if there are \ (3\) numbers, the median will be the \ ( (3+1)\div {2}=...
If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing. If x<y, x is less than y. If x>y, x is greater than y. If x≪y, x is much less than y. If x≫y, x is much greater than y. If x≤y, x is less than or equal to y. If x≥y, x is greater than or equal to y.

To determine the median of numbers in the data set, simply find the middle value.
Sep 19, 2016 · What happens when we have two values that are not equal? There are other symbols that we can use to indicate relationships between numbers: the inequality symbols! The best-known symbols of inequality are “greater than” (>) and “less than” (<) .
