Question 2: What does approximation mean in primary school mathematics? It is close, accurate and approximate in numbers.

Question 3: What does approximation mean in primary school mathematics? What is the approximate answer?

10 divided by 3

It is approximately equal to 3.

Approximate expression is ≈ (10 divided by 3≈3).

Often used when the answer can't be expressed in a normal way, such as 10 divided by 3, and the correct answer is 3 (called an infinite cycle decimal) .50000.000000000105

Question 4: What does about mean in math problems? About in math problems means "approximate" and "about".

Question 5: What does reduction mean in mathematics? For example, I still used to call it reduction,,,,

Meaning: Changing a fraction into an equal fraction with smaller numerator and denominator is called a reduced fraction.

(that is, the numerator and denominator of a fraction are divided by the common factor at the same time, and the value of the fraction remains unchanged. This process is called division. )

Question 6: How to explain the meaning of "about" in primary school mathematics textbooks is "about", "approximate" and "about equal to", that is, it does not require accurate values, but only approximate values.

Question 7: "

For example: A, B, C and D are not zero. A: B = C: Dad = BC.

?

Question 8: What does it mean to check the contract in primary school mathematics? About dà yuyu (1) [About]: Almost identical in number, quantity or time; Probably.

"About" and "about" in primary school mathematics textbooks have the meanings of "approximate" and "about equal", that is, they are not exact numerical values, but close to accuracy and approximation.
