What this step asks
Get 15 answers right in 60 seconds on Subtraction. That is one correct answer every 4 seconds on average, and it takes you into operand band 3 of 5: the numbers grow after every 5 correct answers.
The numbers behind the target
- The run opens with 9 − 3.
- In band 3 the numbers on screen range from 14 to 177.
- Wrong answers and skips cost time but do not take correct answers away.
Before you start
Halfway up, slips cost more than slowness. Aim for a clean run before a quick one.
The run code fixes the tasks, so every retry is the same course. What you learned on the last attempt still applies.
