Assuming the computer could operate addition of negative values the solution would be to add the additive inverse. For example, instead of subtracting 5 - 4 = 1, you would end the addition problem 5 + (-4) = 1. Note that in the second case the "-" was not a subtraction sign but rather a negative sign. In algebraic terms: If x - y = c then x + (-y) = c.
computers persform substraction by addition i.e substraction by 2'complement...
for instance,
if u want to substract 9 - 5
the first thing the computer will do is it will convert the numbers into its binary equivalent i.e.
9's binary equivalent is 1001 and
5's binary equivalent is 0101
then it negate the 0101 to 1010 (all zero's become one's & all one's become zero's)
then it will add the nine's binary equivalent 1001 with
the complement of 5's binary equivalent +1010
-----------------
the number we get is 1 0011
now we will make it 2's
complement by adding 1 1
----------------
0100 this binary equivalent of 4(9-5)
if you understand then send some feedback....
Don't know where you got the idea that computers can only add. Computers can perform all mathematic equasions by converting the numbers to binary form and performing the operation at a machine language level, then converting back to decimal or whatever number system you are using.
Computer can perform Both of them in binary level (0,1)multiplication and Division is done by using subtraction and addition property
it uses an additive inverse
By using division, multiplication, addition or subtraction
BIDMAS B = Brackets I = Index D = Division M = Multiplication A = Addition S = Subtraction
Operation symbols in mathematics are used to represent mathematical operations, such as addition (+), subtraction (-), multiplication (ร), and division (รท). These symbols are used to perform calculations and denote relationships between numbers or variables.
It was the first calculator that could perform all four arithmetic operations: addition, subtraction, multiplication and division.
Operations such as addition and subtraction
The four primary arithmetic operations a computer program can perform are addition, subtraction, multiplication and division.2 + 3 = 5 is an example of addition9 - 7 = 7 is an example of subtraction2 x 3 = 6 is an example of multiplication10 / 2 = 5 is an example of division
Addition or subtraction
An abacus is an ancient form of the modern day calculator.
Because that's how Intel designed it. The 8085 is an 8-bit computer operating on a 16-bit address space.
An adding machine is a mechanical or electromechanical calculator which could perform addition and subtraction.
computer can perform input, process, output, and storage
Yes. In windows its often located in Start > Programs > Accessories > Calculator. They perform this using a math processor built into the CPU (Central Processing Unit). Older computers had a separate math processor called a Math-CoProcessor
