Answer:
Estimate: You can easily know to look at 45 and 32 in the ten thousands place and to add them together, which is 77. So, the answer is going to be around 77,000, but when you look at the entire numbers, you can tell 846 plus 185 is going to be over a thousand. So, if you know 45,000 plus 32,000 is 77,000 and 846 plus 185 is over a thousand, you should add 77,000 and 1,000 together to make an estimate of 78,000.
(This is my way of estimating for this problem, but everyone has different ways of thinking about it!!)
Value: 45,846+32,185=78,031
Since the estimate was only 31 away from the actual answer, you know the estimate was pretty accurate!
Hope this helped you out; have an amazing day!!! :3
