Have you ever memorized or written down numbers while performing complex calculations? Intuitive Memory Calculator solves this problem with multiple memory slots that make it easy to store and retrieve numbers for multistep calculations! Simply tap a memory slot to store a number and tap it again to retrieve a stored number unlimited times. When you ready to clear a memory slot, swipe up on that slot and tap Delete. Additionally, you can now access 25 of your most recent calculations. Many traditional calculators with memory would have up to five buttons (MS, MR, MC, M+, or M-) just to allow you to keep track of one number! Intuitive Memory Calculator has three memory slots which allow you to keep track of three different numbers and each slot was designed to take up no more space than any other button in this calculator.
