Chain Calculations in ALG Mode
To do a chain calculation, you don’t need to press
}
after each operation, but
only at the very end.
For instance, to calculate
360
12x750
you can enter either:
z 750 § 12 } z 360 } or
z 750 § 12 z 360 }
In the second case, the
z
key acts like the
}
key by displaying the result of 750
× 12.
