What this step asks
Get 20 answers right in 60 seconds on Subtraction. That is one correct answer every 3 seconds on average, and it takes you into operand band 4 of 5: the numbers grow after every 5 correct answers.
The numbers behind the target
- The run opens with 4 − 2.
- In band 4 the numbers on screen range from 13 to 587.
- Wrong answers and skips cost time but do not take correct answers away.
Before you start
The top steps ask for a clean and steady run. Take a short break between attempts; a fresh try tends to go further than a fifth one in a row.
The run code fixes the tasks, so every retry is the same course. What you learned on the last attempt still applies.
