Get the biggest number possible. 200 + 520 452 – 102 222 / 11 15 \times 15 \times 2 X 0 1 2 3 4 5 6 7 8 9
The Correct Answer and Explanation is:
numbers:
Given:
- 200 + 520
→ 720720720 - 452 – 102
→ 350350350 - 222 / 11
→ 20.1820.1820.18 (Actually: 222÷11=20.18222 ÷ 11 = 20.18222÷11=20.18), but assuming they meant whole numbers only, possibly meant 22011=20\frac{220}{11} = 2011220=20 - 15 × 15 × 2
→ 225×2=450225 × 2 = 450225×2=450 - X 0
→ Anything × 0 = 0 - Digits listed: 1 2 3 4 5 6 7 8 9
→ Implies we can use these digits possibly to create a new number.
Critical Point: The phrase “Get the biggest number possible.”
The presence of X 0 (multiply by 0) is a trap. Anything multiplied by 0 becomes 0, so any expression containing that will not lead to the biggest number.
Also, the final line with:
1 2 3 4 5 6 7 8 9
suggests you can freely use those digits, perhaps to form the biggest number you can.
✅ Correct Answer: 987654321
✔️ Explanation
LEVEL 42 challenges the player to “Get the biggest number possible,” providing a mix of equations and digits. At first glance, you might feel compelled to compute all expressions. The equations like 200 + 520 = 720, 452 – 102 = 350, and 15 × 15 × 2 = 450 provide valid numerical results, but none are particularly large. The “X 0” expression is a deliberate distraction—it’s a trap. Multiplying anything by 0 will always result in 0, which is certainly not the biggest number.
Next, observe the line:
“1 2 3 4 5 6 7 8 9”
This seems out of place if it’s just a reference. But if we interpret it as a prompt to use these digits, something interesting emerges.
If we arrange the digits 1 through 9 in descending order, we get 987654321, which is the largest possible number you can form using each digit exactly once. There are no instructions that limit how you use the digits—no mention of using operators, preserving the order, or restricting repeats.
This level is testing not your arithmetic skills, but your ability to recognize red herrings and creatively use the resources given. By ignoring misleading calculations and focusing on the digits, the clever solution is to form 987654321, which dwarfs all the other numerical options.
Therefore, the correct and biggest number possible is:
✅ 987654321
