„Função de memória

zPressione [ M+ ] para adicionar um resultado à memória corrente. Pressione [ 2nd ] [ M– ] para subtrair o valor da memória corrente. Para rechamar o valor na memória corrente, pressione [ MRC ]. Para apagar a memória corrente, pressione [ MRC ] duas vezes. Veja Exemplo 4.

zA calculadora tem dez variáveis de memória para uso repetido : A, B, C, X, Y, M, X1, X2, PROG1 e PROG2. Você pode armazenar um número real em variáveis A, B, C, X, Y, M, X1, X2 e duas expressões em PROG1 e PROG2. Veja Exemplo 5.

*[ P/V RCL ] rechama todas as variáveis.

*[ SAVE ] deixa você armazenar valores às variáveis.

*[ 2nd ] [ RECALL ] rechama o valor da variável.

*[ 2nd ] [ CL-VAR ] apaga todas as variáveis exceto PROG1, PROG2.

*[ 2nd ] [ CL-PROG ] apaga os conteúdos de PROG1, PROG2.

(Nota) : Além de pressionar tecla [ SAVE ] para armazenar um valor, você também pode atribuir valores à variável de memória M por [ M+ ] ou [ 2nd ] [ M– ]. Contudo, qualquer coisa atualmente armazenado em variável M será apagado e substituído com o valor recentemente atribuído.
