This may seem hard for someone to figure the answr out in few seconds, because it has 3 numbers for each space. But there are many ways you can figure it out.
One easy way is to focus on the numbers in the hundreds, and forget about the other numbers for now. Subtract them from the other numbers, then start subtracting the smaller numbers. For example, 123, you will look at it as 100, then subtract it from the higher or lower number, then you can focus on 23. This is how it looks:
123 - 587 = 587 - 100 = 487 487 - 23 = 464 Once you have 464, add the (-) sign next to it, because the above equation is 123 - 587, not 587 - 123.
The answer will be -464
Or, if you have other ideas, then go ahead and use it ass long as the final answer is correct.
