What operations do I pick to get to 6 in Brain Test 5 Level 19?

Starting from 0, select +1 (total=1), then +2 (total=3), then x2 (total=6). All three operations come from the left column. Avoid the right-column negative numbers.

How do I get to 28 in Brain Test 5 Level 19?

Select +7 first (total=7), then x4 (total=28). Do not start with +11 — that path leads to an unreachable state. The +7 then multiply-by-4 route is the only clean solution.

Brain Test 5 Level 19 Walkthrough

medium

Brain Test 5 Level 19 is a sequential math puzzle — select operations in order to reach the target number starting from zero. Get to 6 with +1, +2, x2. Get to 4 with just +4. Get to 28 with +7 then x4.

Board Notes

Layout: Level 19 opens with a math operation board. A target number is displayed at the bottom (e.g., "6"). Two columns of operations are shown — left column has positive and multiplication operations, right column has negative and division operations. A running total starts at 0.
Goal: Select operations in sequence to reach the target number exactly. Three challenges run in order with increasing target numbers. The running total is displayed after each selection.
Opening: Part 1 ("Get to 6"): tap +1 (total=1), then +2 (total=3), then x2 (total=6). Part 2 ("Get to 4"): tap +4 directly (total=4). One operation reaches the target. Part 3 ("Get to 28"): tap +7 (total=7), then x4 (total=28).
Danger Zone: In Part 1, using any right-column negative operation early drops the total and makes 6 unreachable from the remaining operations. In Part 3, selecting +11 first (total=11) leaves no clean path to 28 — the +7 then x4 route must be chosen first.
Mechanics: Level 19 is a forward-planning math selection puzzle. Unlike the pattern puzzles of Level 17, this level requires considering the effect of each operation on the running total before selecting it. Multiplication operations are more powerful than repeated additions.

Quick Tips for Brain Test 5 Level 19 (spoiler-free)

Avoid the right-column negative operations in all three parts — they lead the total away from each target.
For "Get to 28," check for a multiplication shortcut before adding. +7 and x4 is faster and more reliable than any multi-addition path.
The target number shown at the bottom is the constant goal. If your running total passes it, you have gone too far.

How to Solve Brain Test 5 Level 19 — Full Solution

Part 1 — "Get to 6": tap +1 (total becomes 1), then tap +2 (total becomes 3), then tap x2 (total becomes 6). All three come from the left column.
Part 2 — "Get to 4": tap +4 from the left column. The total goes immediately from 0 to 4.
Part 3 — "Get to 28": tap +7 from the left column (total becomes 7), then tap x4 (total becomes 28). Do not select +11 first.
All three targets are reached. The level ends.

Common Mistakes to Avoid

Selecting any right-column negative operations in Part 1 — they push the running total in the wrong direction.
Selecting +11 as the first operation in Part 3 (total=11) — this leaves no path to 28 with the remaining operations.
