The word “of” typically indicates multiplication, while the word “off” is not used in math.

## So let’s take a deeper look

In mathematical expressions, “of” and “off” are two different words with distinct meanings. The word “of” is typically used to indicate multiplication or a ratio between two numbers. For example, “5% of 100” means 5 multiplied by 100 divided by 100, which equals 5. Similarly, “2/3 of 6” means 2 multiplied by 6 divided by 3, which equals 4.

On the other hand, the word “off” is not used in math to indicate any operation or relationship between two values. It is simply a preposition that means “away from” or “not in contact with”. Therefore, the word “off” does not have any mathematical definitions or applications.

According to MathIsFun, a website dedicated to making math easy to understand, the word “of” is commonly used in a range of math concepts and formulas, such as percentages, ratios, and proportions. Moreover, using the word “of” in mathematical language can help clarify relationships between different values, making it easier to solve problems and make calculations.

In conclusion, the difference between “of” and “off” in math is significant. While “of” is a commonly used preposition that indicates multiplication or a ratio between values, “off” does not have any mathematical meanings or applications.

“Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.” -William Paul Thurston

Word | Meaning | Example |
---|---|---|

Of | Indicates multiplication or ratio between two values | 5% of 100 = 5 |

Off | Preposition meaning “away from” or “not in contact with” | The book is off the table |

## Answer in video

This video on “Learning Approximation and Estimation | Math” explains the difference between approximation and estimation. Approximation refers to a value or quantity that is very close but not exactly correct, whereas estimation involves a rough calculation of a number’s value or quantity. Understanding place value and significant figures is important for accurate estimation. Significant figures represent the accuracy of our estimate and the rule is that any division that is not zero is significant. For numbers containing decimal points, the trailing zeroes may or may not be significant.

Let’s do round up, round down and simple round for 2.4 and 2.6 (2.5 behaves like 2.6 usually, though sometimes it behaves like 2.4)

Round down: both round to 2

Round up: both round to 3

Round: 2.4 goes to 2, 2.6 goes to 3: the closest integer.(when rounding to integers: if you want to round to tens you’d get 0 in every case, to tenths you’d preserve all numbers)

**‘Of’ is used to show a relationship or connection between someone or something to another.**‘Off’ means away from someone or something, i.e. it expresses the act detachment from a person, place or object.

Let’s see some examples. Explanation: In math, ‘of’ is also considered as one of the arithmetic operations which means multiplication within the brackets. For example, we need to find one-third of 30.

"of" means times. So if the question asks for 3/4 of 60, you want to work out 3/4 x 60 which is the same as working out (3 x 60) and then dividing the answer by 4. So the answer would be 45.

**finding the difference between two numbers**. To find the difference between two numbers, take the larger one and subtract the smaller one. For example, the difference between 10 and 15 is 15 – 10 = 5. What is meant by difference? The difference is the distance between two values.

**Of is a preposition**, which is used to show some connection with the other word, or part of the sentence. As against, Off is commonly used as an adverb, but it can also be used as a noun, verb, adjective and preposition.

**adverb or a preposition**. In both cases, it indicates separation or disconnection. Here’s a tip: Want to make sure your writing shines?
