give an example of addition problem in which you would and would not group the addends differently to add

aleksandrvk [35]

An example of a problem where I would not group the addends differently is:

3+2+4.

An example of a problem where I would group the addends differently is:

2+5+8.

Explanation:

In the first problem, I would not group the addends differently before adding. This is because I cannot make 5 or 10 out of any of the numbers. We group addends together to make "easier" numbers for us to add, such as 5 and 10. If we cannot do that, there is no reason to regroup the addends.

In the second problem, I would regroup like this:
2+8+5

This is because 2+8=10, which makes the problem "easier" for us to add. Since we can get a number like this that shortens the process, we can regroup the addends.

77julia77 [94]

Given:

A line passes through the points (2,-1) and (1,-5).

To find:

The equation of the line.

Solution:

If a line passes through the two points, then the equation of the line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$
