An abacus measures nothing, it is a device used for calculation
addition
No. It is solving brackets or parentheses.
In China in 1960
Abacus was the first calculating device invented by the Chinese.
Because many people do not understand the differencebetween a manual calculation aid, a calculator, and an automatic computer.A manual calculation aid is a manual device where the user needs to fully understand the calculation and how to manipulate the parts of the device to perform every step of the calculation. The user must perform every step of the calculation on the device himself by hand. An abacus is a manual calculation aid. A sliderule is also a manual calculation aid.A calculator is a manual device where the user needs to understand the calculation he wants to perform but the device can perform the detailed steps itself. The user must request each step of the calculation from the device by hand.A computer is an automatic device that once set up (programmed) will perform the calculation anytime it is needed, without any attention from the user and even if the user has no understanding of the problem at all (the designer of the program is the only one that had to understand the problem).
The device that is used for calculation is a calculator. However, in computers, the part of the device that is used for computation would be the CPU, or the central processing unit.
no, first mobile device was a knife...
An abacus measures nothing, it is a device used for calculation
the least count of the device must be noted first. the uncertainty of this will be the least count divided by 2. so if its is 0.1 then it will be 0.05
Parentheses
The devices could do most of the calculation work by itself
computer is a electronic device it mean many calculation opetator
shotrest path first calculation
Yes and it was called an abacus counting device.
Clocks
Suan-pan tray, which developed in China around 200BC. Suan-pan is an abacus for various calculations including counting, addition, subtraction, multiplication, division, square roots and cube roots. This is recored earliest device use for mathematical calculation
