Digital Logic Fundamentals: Arithmetic Operations and Boolean Algebra
This covers the core arithmetic operations in digital logic, which are fundamental to how computers process data.
1. Binary Arithmetic
Binary arithmetic uses only the digits 0 and 1. The key difference from decimal arithmetic is that a carry is generated when the sum reaches 2 (which is 10_2).
A. Binary Addition
| Rule | Description |
|—|—|
| 0 + 0 | 0 (Carry 0) |
| 0 + 1 | 1 (Carry 0) |
| 1 + 0 | 1 (Carry 0) |
| 1 + 1 | 0 (Carry 1 to the next position) |
| 1 + 1 + 1 | 1 (Carry 1 to the next position)

Birthday Celebration
Last weekend, I celebrated my birthday with my friends and family. My house was decorated with colorful balloons and a big banner that said “Happy Birthday.” The party started at 5 in the afternoon. We ate pizza, chocolate cake, and some tasty snacks. Everyone sang “Happy Birthday,” and I blew out the candles. After eating, we played fun games like limbo and guessing the movie. We were laughing the whole time. I also got many gifts, including a backpack and some books.
Principles of Flight
A Trial Balance is a financial report that lists the names and balances of all the accounts in the general ledger of a business at a specific point in time. Its primary purpose is to verify the mathematical accuracy of the double-entry bookkeeping system by ensuring that the total of all the Debit balances equals the total of all the Credit balances.
📝 Errors Revealed by the Trial Balance -Errors that cause the total of the debit column to be unequal to the total of the credit column are revealed
Cell Biology Fundamentals: Cycle, Control, and Structure
Cell Cycle: Growth, Replication, and Division
The cell cycle is an ordered sequence of events enabling a cell to grow, replicate its DNA, and divide into two genetically identical daughter cells, ensuring accurate genetic transmission. It comprises interphase (G1, S, G2 phases) and the mitotic (M) phase (mitosis and cytokinesis).
- G1 Phase: The cell grows metabolically, synthesizing proteins and organelles while assessing environmental conditions at the restriction point before committing to division.

Unit 2 – Rediscovering the Lyric: The Sonnet
A sonnet is a short, intricate poem of 14 lines that expresses complex emotions in a limited space. Reading a sonnet feels like opening a tiny jewel box — each time, you discover something new. Though small, it requires great craftsmanship and precision.
The sonnet was first developed in Sicily in the 13th century by Giacomo da Lentini and later perfected by Petrarch in Italy. It spread across Europe and became a mark of sophistication in Tudor England.

Gas Exchange Fundamentals
Gas exchange is the process where an organism takes in oxygen and eliminates carbon dioxide. Oxygen is essential for respiration and must reach every cell. Carbon dioxide is a waste product of respiration that must be removed from the body. Gas exchange occurs via diffusion across a gas exchange surface. Oxygen diffuses from air or water, either into the blood for transport to the cells or directly into the cells. Carbon dioxide diffuses from the cells or the blood back
