A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
5 k 2 3 / p To evaluate (+ ()): (v computes the square root of the top of the stack and _ is used to input a negative number): 12 _3 4 ^ + 11 / v 22 - p To swap the top two elements of the stack, use the r command. To duplicate the top element, use the d command.
ANITA Mk VIII. The ANITA Mark VII and ANITA Mark VIII calculators were launched simultaneously in late 1961 as the world's first all-electronic desktop calculators. [1] [2] Designed and built by the Bell Punch Co. in Britain, and marketed through its Sumlock Comptometer division, they used vacuum tubes and cold-cathode switching tubes in their logic circuits and nixie tubes for their numerical ...
GNOME Calculator, a software calculator. A software calculator is a calculator that has been implemented as a computer program, rather than as a physical hardware device. They are among the simpler interactive software tools, and, as such, they provide operations for the user to select one at a time. They can be used to perform any process that ...
The first scientific calculator that included all of the basic ideas above was the programmable Hewlett-Packard HP-9100A, [5] released in 1968, though the Wang LOCI-2 and the Mathatronics Mathatron [6] had some features later identified with scientific calculator designs.
Apart from programmer functions, the calculator's abilities are limited to basic arithmetic (and reciprocal and square root), [3] which meant that typical users would also make use of a general scientific calculator. Floating-point numbers are only supported for base 10. However, it is still far more powerful (though also much more expensive ...
The product of two variables ranging from 90-99 will result in a 4-digit number. The first step is to find the ones-digit and the tens digit. Subtract both variables from 100 which will result in 2 one-digit number. The product of the 2 one-digit numbers will be the last two digits of one's final product.
if the last digit of a number is 4 or 6, its square ends in an odd digit followed by a 6; and; if the last digit of a number is 5, its square ends in 25. In base 12, a square number can end only with square digits (like in base 12, a prime number can end only with prime digits or 1), that is, 0, 1, 4 or 9, as follows:
