Using school half-up rounding, round the timing 12.995 to two decimal places and enter the number.
Correct answer
13 ± 0.001
Explanation
The thousandths digit is 5, so the hundredths digit 9 increases and carrying changes 12.995 to 13.00 at two-decimal precision. Entering 12.99 would ignore the half-up rule and the carry across both 9s.
