## How do you subtract in 8085?

In 8085, the SUB instruction is used 2’s complemented method for subtraction. When the first operand is larger, the result will be positive. It will not enable the carry flag after completing the subtraction. When the result is negative, then the result will be in 2’s complemented form and carry flag will be enabled.

**How we can subtract two bits in microprocessor?**

Algorithm “

- Load 00 in a register C (for borrow)
- Load two 8-bit number from memory into registers.
- Move one number to accumulator.
- Subtract the second number with accumulator.
- If borrow is not equal to 1, go to step 7.
- Increment register for borrow by 1.
- Store accumulator content in memory.

### Which instruction is used for subtraction of two 16 bit numbers?

Hence we have subtracted two 16 bit numbers. Get the LSB in L register and MSB in H register of 16 Bit number. Exchange the content of HL register with DE register….Program “

MEMORY ADDRESS | MNEMONICS | COMMENTS |
---|---|---|

200A | SUB L | A<-A-L |

200B | STA 2054 | 2054<-A |

200E | MOV A, D | A<-D |

200F | SBB H | SUBTRACT WITH BORROW |

**How can I add two 16 bit numbers in 8086?**

8086 program to add two 16-bit numbers with or without carry

- Load 0000H into CX register (for carry)
- Load the data into AX(accumulator) from memory 3000.
- Load the data into BX register from memory 3002.
- Add BX with Accumulator AX.
- Jump if no carry.
- Increment CX by 1.
- Move data from AX(accumulator) to memory 3004.

#### How do you subtract 1 in binary?

Hence, when we subtract 1 from 0, we need to borrow 1 from the next higher order digit, to reduce the digit by 1 and the remainder left here is also 1. Read other binary operation here….Binary Subtraction Table.

Binary Number | Subtraction Value |
---|---|

1 “ 0 | 1 |

0 “ 1 | 1 (Borrow 1 from next high order digit) |

1 “ 1 | 0 |

**How do you write 2 in binary?**

When you get to “two”, you find that there is no single solitary digit that stands for “two” in base-two math. Instead, you put a “1” in the twos column and a “0” in the units column, indicating “1 two and 0 ones”. The base-ten “two” (210) is written in binary as 102.

## What are the rules of subtraction?

To subtract integers, change the sign on the integer that is to be subtracted.

- If both signs are positive, the answer will be positive. Example: 14 – (-6) = 14 + 6 = 20.
- If both signs are negative, the answer will be negative.
- If the signs are different subtract the smaller absolute value from the larger absolute value.

**What are the 3 parts of subtraction?**

What Are the Three Parts of Subtraction?

- Minuend: The number from which we subtract the other number is known as the minuend.
- Subtrahend: The number which is subtracted from the minuend is known as the subtrahend.
- Difference: The final result obtained after performing subtraction is known as the difference.

### What are the 4 properties of subtraction?

Properties of subtraction:

- Subtracting a number from itself.
- Subtracting 0 from a number.
- Order property.
- Subtraction of 1.

**What is the result of subtraction called?**

Formally, the number being subtracted is known as the subtrahend, while the number it is subtracted from is the minuend. The result is the difference.

#### What is the first number in subtraction called?

minuend

**What are the numbers you subtract called?**

Subtraction is the operation of taking the difference of two numbers and . Here, is called the minuend, is called the subtrahend, and the symbol between the and is called the minus sign.

## What is the bigger number in subtraction?

The subtrahend is the number that is subtracted from the minuend and it must be the smaller number then minuend for the difference to be positive. The difference is the result of the subtraction. Therefore, from above discussion we observe that the greater number in the subtraction is called the minuend.

**What are subtraction strategies?**

Students break apart one of the numbers. Subtract the tens to get a new difference. Then subtract the ones from that number.

### What is it called when you divide two numbers?

When you divide two numbers the answer is called the quotient. The quotient of six divided by two is three.

**How do you do 2 digit division?**

Divide the first number of the dividend (or the two first numbers if the previous step took another digit) by the first digit of the divisor. Write the result of this division in the space of the quotient. Multiply the digit of the quotient by the divisor, write the result beneath the dividend and subtract it.

#### What is the quotient of 24 is divided by 48?

What is the Quotient and Remainder of 24 Divided by 48? The quotient (integer division) of 24/48 equals 0; the remainder (left over) is 24.
