With the Exact/Approx set to "AUTO" in the mode menu, how can I get approximate answers without going and switching it to approx then recalculating?

George Jones said:Put a decimal in one of the numbers, i.e., instead of entering 4 / 3, enter 4. / 3. If you forget, or if you an exact number answer that you want converted to a decimal, just x (times) 1.
Try both to see how they work!

An exact answer on TI-89 is a solution that is represented as a simplified mathematical expression, while an approximate answer is a decimal or numerical value that is rounded to a specific number of decimal places.
To switch between exact and approximate answers on TI-89, you can press the "Exact" or "Approx" button on the calculator, or use the shortcut keys "Ctrl+Enter" for exact answers and "Ctrl+0" for approximate answers.
Yes, you can change the number of decimal places for approximate answers on TI-89 by going to the "Mode" menu and selecting "Exact/Approx" options. From there, you can choose the desired number of decimal places.
The answer on TI-89 will be displayed as an exact answer if it is a simplified mathematical expression, and it will be displayed as an approximate answer if it is a decimal or numerical value.
Yes, you can use both exact and approximate answers in the same calculation on TI-89. Simply use the "Exact" or "Approx" buttons to switch between the two types of answers as needed.
