Growth rate calculation formula: Growth rate (growth percentage point) % = (current growth level and quantity - Base growth level and quantity)\/ Base growth level and quantity ×100%, where the base period is the level of a selected year as a reference, so that the growth level of other periods can be compared with the base period, so as to measure the current growth level. If we want to calculate the growth rate of last month, we should take the growth amount of the previous month as the growth level and quantity of the base period; In order to calculate the growth rate of last year, we can use the growth level and quantity of the previous year as the base period. The calculation method of growth rate and growth amount above the base period base: expected growth amount = base period base (base period base × expected growth rate) The calculation of expected growth amount is widely used in the calculation of expected price, expected output, and expected point, which is often used in economic life and is also an aspect of the content of the preparation of the plan.
If you increase 1000 by 2 points, 1000 x 2%=1000 x 0.02=20.
According to the requirements of this question, this is a simple mathematical percentage point problem, no other factors are involved, so directly calculate the percentage point.
The calculation method of percentage points is that a number multiplied by a few percent is the result, for example, 10 increased by 2 points, is 10 x 2%=10 x 0.02=0.2.
So 1000 increases by 2 points, so 1000 x 2%=1000 x 0.02=20.

Let's take an example: How to calculate what the growth rate is? For example, it was 100 this month and 40 last month. What percentage increase is this month compared to last month?
two
So its percentage increase is (100-40)\/40=150%, subtract this month from last month and divide by this month to get the percentage increase.
three
Let's look at the same year's growth percentage algorithm, if last year was 100, this year is 120, then its growth ratio calculation formula is 120\/100-1=20%.

However, this formula only applies to the numbers before and after the two data are positive, if there is a positive and a negative or both are negative,
