Make three three-digit numbers that add up to as close to 1000 as possible using the digits 1- 9 only one time each.

There are multiple answers that would get 999 such as 247 + 563 + 189 or 164 + 237 + 598.

Is 1000 even possible? Here is a link to a Geogebra to help you check.

The puzzles above are all about Order of Operations:

50 + 50 – 25 x 0 + 2 + 2
50 + 50 – 0 + 2 + 2
104


48 divided by 2(9 + 3)
48 divided by 2 x 12
Now go from left to right
24 x 12
288

A: 454585

9 5 5 =?

9×5 = 45 (first and second)

9×5 = 45 (first and third)

Sum of 45+45 = 90 and from this deduct center number 5 = 85
