The video comprehensively explores the extensive features and functionalities of the Windows Calculator, revealing it as a powerful tool beyond basic arithmetic. It underscores key elements such as the “Always On Top” button, the history and memory functions, and various keyboard shortcuts (e.g., Alt+H for the menu, F9 for toggling number signs). The speaker details the differences between the C (clear all) and CE (clear entry) buttons, and covers advanced scientific functions like exponents, logarithms, and trigonometric operations. Further discussed are the DMS button for angle conversions, the graphing calculator for plotting equations and analyzing functions, and the programmer calculator for converting numbers between bases and performing bitwise operations. The video also delves into the date calculator for calculating differences between dates, and various converters for units like currency, volume, length, weight, temperature, and data sizes. It clarifies the confusion between terms like gigabytes and gibibytes, explaining storage discrepancies due to different measuring bases. The presenter wraps up by encouraging viewers to subscribe for more detailed tech content.

In this part of the video, the speaker discusses the extensive features of the Windows Calculator, highlighting that it offers more functionality than most users might realize. Key features covered include the “Always On Top” button, which keeps the calculator visible while using other programs, and the expandable menu accessible via the hamburger icon. This menu reveals additional options such as History and Memory. The speaker explains how users can copy and paste entire equations into the calculator and details the memory functionality with MS (Memory Store) and MR (Memory Recall) buttons. Additionally, the video covers various keyboard shortcuts, such as using Alt+H to open the hamburger menu and specific combinations to switch between different types of calculators (regular, scientific, currency, volume, etc.).

### 00:03:00

In this part of the video, various calculator shortcuts and functions are explained. Key points include using Alt+Up to put the calculator in always on top mode and Alt+Down to remove it from that mode. Pressing F9 swaps the displayed number between positive and negative, and Shift+2 calculates the square root. In Scientific mode, F3, F4, and F5 toggle between degrees, radians, and grads, respectively.

The video also clarifies the % button usage, showing how to calculate percentages and add or subtract percentages directly. The difference between the C and CE buttons is explained, with C clearing all entries and CE only clearing the current entry.

The scientific calculator section covers additional operations such as exponents, logarithms, and factorials. It introduces the “2nd” button for toggling additional functions, the EXP button for exponential notation, and the modulus operator for finding remainders. Trigonometric functions and their inverses are also discussed, along with the absolute value, floor, and ceiling functions to round numbers differently based on their values.

### 00:06:00

In this part of the video, it explains various features of advanced calculators. The Rand button generates a 32-digit random number between zero and one. The DMS button converts angles from degrees to a degrees, minutes, and seconds format, and back. The segment then moves to the graphing calculator, demonstrating functions like Y=MX+B, sliding between values, plotting multiple expressions, analyzing functions for maxima, minima, and inflection points, and graphing inequalities. It also shows how to apply absolute value, floor, and ceiling functions to graphs. The programmer calculator is discussed next, converting numbers into different bases such as hexadecimal, octal, and binary. It introduces bit toggling for learning binary code, and various bitwise functions.

### 00:09:00

In this part of the video, the presenter explains how different mathematical and bitwise operations can be performed using a calculator. By using examples like 20 AND 50 resulting in 16, and 20 OR 50 resulting in 54, the presenter clarifies how binary values interact under these operations. They note that the bit shift operation is complex and not explained in detail.

The video then transitions to the date calculator, which helps users calculate the difference between dates or add/subtract days using a calendar interface. For converters, several options are discussed, including currency, which requires internet updates for exchange rates, and volume, where interesting distinctions like the difference between milliliters and cubic centimeters and US vs. UK units are noted.

The segment concludes by exploring various converters, such as length, weight, temperature, and data. The presenter highlights the difference between units like megabytes and mebibytes, explaining that gigabytes, megabytes, and terabytes follow base 10, while gibibytes, mebibytes, and tebibytes follow base two, which often leads to confusion.

### 00:12:00

In this segment of the video, the speaker clarifies why storage devices, like a one terabyte hard drive, appear to have less capacity in Windows (showing 931 gigabytes) due to Windows measuring size in gibibytes and tebibytes but displaying the wrong units. Additionally, there is further confusion because hard drive manufacturers use base 10 values while RAM manufacturers use base 2. The speaker then concludes the video by encouraging viewers to subscribe, enable notifications, and watch another recommended video about alternatives to Windows Explorer.
