For example, 4 is twice that of 2, 6 is three times that of 2, and twice that of 2 is 4.
The question "4 is twice as much as 2" means that 4 is twice as much as 2, that is, doubled. That is 4=2+2=2*2. It is twice that of 2, and "6 is three times that of 2" means (6/2)=3, that is, 6 = 2+2 = 2 * 3.
What is said is actually not a standard. It is ambiguous whether the word "double" means "double" or multiplied by 1 (it depends on the language environment and the actual situation). So the double precision of 2 is 4, and the double precision of 2 is 2*2*2=8, which is unambiguous.
Generally speaking, 4 is twice as much as 2, which is a popular and omitted statement. This statement is wrong in mathematics and should be expressed as 4 is twice as much as 2.
Extended data:
A deep understanding of the word "time";
The word "times" is equivalent to British time.
First of all, we should understand that the word multiple comes from the concept of division, or quotient. In other words, when "multiple" is involved, please switch to the division mode immediately.
Definition: if a is n times that of b, then a divided by b equals n.
For example, a is 1 times of b, then a divided by b equals 1, that is, a equals b; 10 is 1 0 times of1,that is, 10 =1x 10, and10 after this multiplication sign is a multiple.
At the same time, this n cannot be an integer, so there are also decimals and fractions.
For example, A is n times that of B. Of course, you can put it another way: N times that of B is A, so you just need to multiply B by N to get A.
For example, 0.5 times of 3 is 3×0.5 = 1.5.
1.2 times 2 equals 2 times 1.2 equals 2,4.
It is one time: A is 1 times of B, A divided by B equals 1, and A equals B.
It is twice: A is twice that of B, A divided by B equals 2, A equals B times 2, and this is 2B.
Double: A is more than B 1 times.
Double: A is more than B 1 times, and A-B divided by B equals 1, so A-B equals B times 1, so A equals 2B.
