How can you subtract two numbers? Don't panic, don't panic, speak clearly today Okay, your M was subscription now to bit number Alright, we won't do it today. How can you subtract two numbers? Don't panic, don't panic, speak clearly today India Jail here too, first me, first juice Your logic is slightly off, but the code is different. I'm asking you about the code you've written. You have written here What is A in this? What is the name of this disorder? Accumulator Can you tell me why you call it an accumulator? Accumulator? Because this data accumulates, it is a type of special register, which can be used both as a source and as a destination. Okay, what are registers, do you have an idea, what are they? There's surely something wrong. There's surely something wrong. A register is a device that stores data, where does it reside, what happens inside? It sits within. You wrote about him, move A, B So, do we ever move it? Store the data there, like a storage place for the data. Was he ever taken there to store data? What do we do when data is sent from one register to a second register? MOE But when data is sent immediately to us in the register, what do we do? MVER The exact correct answer is Cheers After that, you wrote here: add B What does "add b" written here mean? Who to add? The accumulator with b When we write "add b," which group's instruction is "add b"? Which group's instruction is addition? What is this? Is addition an instruction of the arithmetic group? Listen very carefully, what I'm about to tell you? Chapter 2's WYV (What You've Learned) questions are very easy. The questions given to you are asked right there. Read instruction 74 carefully. advising mode read which groups are there Read it carefully. Yavi: It's easy, also good in exams, can score well Our focus shifts to the fact that there are 74 questions and instructions. Read whom you should read, don't read whom you shouldn't read, practice Look carefully, and it becomes easy So, focus, first listen to the question Now I wrote "add b", the meaning of "add b" is that the accumulator is hidden there. So it means all the arithmetic operations that exist The accumulator is always hidden there. Which other group has an accumulator hidden within it? logical instruction What is the accumulator in arithmetic instruction and logical instruction always? It exists there, but we can't see it, just like we were told to add b "b" means "place b"; it is not shown, nor written. There exists one there, right? add b, how many bytes is the instruction? It is 4 bytes. No mother Okay, tell me, what is a byte and what are bits? Byte and bits are very common questions that will be asked of you in part 2. So, bytes, bits—you should have an idea by now No idea? Get good at the board, so you don't make mistakes You can get such marks in the board exam. Next time, we will be very careful.
