Designing numerical stimuli

Hello. I need to create numerical stimuli for an experimental task that requires selecting whether a 2-digit number is greater than or less than another 2-digit number that remains constant across trials (e.g., 37). For example, on 1 trial they would see 34 and have to respond if it is greater than or less than 37. On the 2nd trial they would see 56 and respond if this is greater than or less than 37. And so on…

My thoughts are that as long as the numbers are not round numbers (10, 20, 30, etc.) then to get the answer correct the person would have to fixate on both digits (which is key for the task). Any feedback, questions, or suggestions on this would be great. Thank you for your time.
