Why is the first quadrant in a coordinate plane on the right hand side?

Ok, 2 questions! Why is the first quadrant in a coordinate plane on the right hand side? How can you compare estimation to rounding?Why is the first quadrant in a coordinate plane on the right hand side?1. Because both the x and y coordinates are positive.

2. Estimating is when you don't know what exactly something is but you make a guess of it, while rounding is when you know the number but you are putting it an easier and simpler form.Why is the first quadrant in a coordinate plane on the right hand side?1. look at the x axis of a coordinate plane... it looks like a number line, right? it's on the right side because on the left side are negative numbers. it wouldn't make sense to have it on the left side, positives come after negatives. and i guess, more often than not, you'd be working with positive numbers.



2. estimation and rounding both aren't exact. they give you "about" however much the number is. they're both good for quick math and deciding about how much something is going to be, but not so great for things that involve exact numbers.



hope that helps! :3
