Use mental math to find the sum of 432 + 250

To start I would add 400 + 200, and that equals 600.

Then I would add 30 + 50, and that equals 80.

And then I have 2 left over.

600 + 80 = 680

Add the left over 2, so 680 + 2

680 + 2 = 682. Your answer is 682.

I hope this helps!

Step-by-step explanation:

Add 432+250 (4+2 is 6 3+5 is 8 2+0 is 2) put the numbers together and get 682

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
