Let's try some other simple operations before trying the more complicated expression used earlier for the algebraic operating mode:
123/32123`32/
424`2Q
3√(√27)27R3@»
Note the position of the y and x in the last two operations. The base in the exponential operation is y (stack level 2) while the exponent is x (stack level 1) before the key Q is pressed. Similarly, in the cubic root operation, y (stack level 2) is the quantity under the root sign, and x (stack level 1) is the root.
Try the following exercise involving 3 factors: (5 + 3) ⋅ 2
5`3+ Calculates (5 +3) first.
2X | Completes the calculation. |
Let's try now the expression proposed earlier:
⎛ |
|
| 1 | ⎞ |
|
3 ⋅ ⎜ | 5 − |

|
| ⋅ 3 |

⎝ | 3 | ⎠ | 2.5 | ||

3` Enter 3 in level 1
5` Enter 5 in level 1, 3 moves to level 2 3` Enter 3 in level 1, 5 moves to level 2, 3 to level 3 3* Place 3 and multiply, 9 appears in level 1
Y1/(3⋅3), last value in lev. 1; 5 in level 2; 3 in level 3
-5 - 1/(3⋅3) , occupies level 1 now; 3 in level 2
*3 ⋅ (5 - 1/(3⋅3)), occupies level 1 now. 23`Enter 23 in level 1, 14.66666 moves to level 2.
3Q Enter 3, calculate 233 into level 1. 14.666 in lev. 2.
/(3 ⋅
2.5Enter 2.5 level 1
!¸ e2.5, goes into level 1, level 2 shows previous value.
