    Let me tell you the meaning of these keys first. MC =It will clear the memory and set its value to 0 MR =It will help you to recall the value the value stored in memory. MS =It will help you to store a value in the memory of your calculator. M+ =It takes the number on the display and add it to the stored value. Let me give you a simple example. 5 x 5 = 25 (on display) MS (stores 30 in memory) 12 x 3 = 36 (on display) M+ (takes 36, adds it to 25, stores result 61 in memory) 3 x 7 = (21) M+ (takes 61, adds 21, stores the result 82) MR (displays the result 82)
