FFFFFFFFFF (for negative) Overflow and Error Conditions The symbol E appears when any of the following conditions occur. Press [ ON/C ] to remove the overflow or error indicator. • When you attempt to perform a function calculation with a number outside the allowable input range. • When you attempt to divide a number by 0. • When you have pressed the [ ( ] key more than 15 times in a single expression. • When any result (whether intermediate or final) or the accumulated total in memory is outside ±9.999999999 . 10 99 • When there are more than six pending operations. If the calculator becomes locked and pressing keys has no effect, press [ M+ ] and [ ENG ] at the same time. This unlocks the calculator and returns all settings to their default values. Basic Calculations The following examples of basic calculations assume that your calculator is in decimal base and with floating point display. Mixed Arithmetic Calculations 1 + 2 . 3 = ? 1 [ + ] 2 [ . ] 3 [ENTER] DEG 7. –3.5 + 8 .2 = ? 3.5 [ +/– ] [ + ] 8 [ . ] 2 [ENTER] DEG 0.5 Parentheses Calculations Operations inside parentheses are always executed first. You can specify up to 15 levels of parentheses in a single calculation. When you enter the first parenthesis, the ( ) indicator appears on the display and remains until each opening parenthesis has a corresponding closing parenthesis. ( 5–2 . 1.5 ) . 3 + 0.8 . (– 4 ) = ?

Memory Calculations • The M indicator appears when a number is stored in memory. • Recalling from memory does not delete the contents of memory. • The memory is not available when you are in statistics mode. • To copy the displayed number to memory, press [ X>M ]. • To clear the memory, press [ 0 ] [ X>M ], or [ CE ] [ X>M ], in that order. 3 . 5 [ CE ] [ X>M ] DEG 0. 3 [ . ] 5 [ M+ ] M DEG 15. + 56 . 7 56 [ . ] 7 [ M+ ] M DEG 8. + 74 – 8 . 7 Total = ? 74 [ – ] 8 [ . ] 7 [ M+ ] M DEG 18.
