7 + 2 = 9
If "increased in so many times," it is multiplication. For example, the number 7 is increased in 2 times. It is necessary to multiply the previous value of the specified number of times, and we get a new meaning:
7 * 2 = 14
As you can see, the numbers in the above examples are the same, and the result is different. It all depends on how to formulate a thought.
