Lesson 30: Using + Addition Arithmetic Operator
Learn how + adds values, works with different data types, and how it differs from += updates.
Lesson 31: Using - Subtraction Arithmetic Operator
Learn how - subtracts values, works with multiple data types, and how it differs from -= updates.
Lesson 32: Using * Multiplication Arithmetic Operator
Learn how * multiplies values, works with multiple data types, and how it differs from *= updates.
Lesson 33: Using / Division Arithmetic Operator
Learn how / divides values, including integer vs float division, and how it differs from /= updates.
Lesson 34: Using % Remainder Arithmetic Operator
Learn how % returns division remainder and how to use it for even/odd and periodic logic.
Lesson 35: Using && Logical AND Boolean Operator
Learn how && combines multiple conditions so code runs only when every required check is true.
Lesson 36: Using ! Logical NOT Boolean Operator
Learn how ! inverts boolean results, simplifies conditions, and improves active-low logic clarity.
Lesson 37: Using || Logical OR Boolean Operator
Learn how || returns true when any condition is true and helps build flexible trigger logic.
Lesson 38: Using == Equal To Comparison Operator
Learn how == compares values, returns true/false, and controls decision branches.
Lesson 39: Using > Greater Than Comparison Operator
Learn how > evaluates thresholds and triggers logic when values exceed limits.
Lesson 40: Using >= Greater Than or Equal To Comparison Operator
Learn how >= handles inclusive thresholds so equal values also pass comparison checks.
Lesson 41: Using < Less Than Comparison Operator
Learn how < checks strict lower-than conditions and how it differs from <= in threshold logic.
Lesson 42: Using <= Less Than or Equal To Comparison Operator
Learn how <= includes boundary values so equal and lower values pass in threshold checks.
Lesson 43: Using != Not Equal To Comparison Operator
Learn how != detects mismatched values and helps build state-change logic.
Lesson 44: Using += Compound Addition Operator
Learn how += updates variables in one step for counters, totals, and loop-based increments.
Lesson 45: Using -= Compound Subtraction Operator
Learn how -= updates variables in one step for countdowns, reducing delays, and step-down loops.
Lesson 46: Using *= Compound Multiplication Operator
Learn how *= updates variables in one step for scaling values and growth patterns in loops.
Lesson 47: Using /= Compound Division Operator
Learn how /= updates variables in one step for reducing values and scaling down loop behavior.
Lesson 48: Using %= Compound Remainder Operator
Learn how %= updates variables in one step using remainder logic for wrap-around counters and repeating patterns.
Lesson 49: Using &= Compound Bitwise AND Operator
Learn how &= keeps selected bits and clears others using masks for safe flag handling.
Lesson 50: Using |= Compound Bitwise OR Operator
Learn how |= sets selected bits with masks while preserving existing bits in flag variables.
Lesson 51: Using ^= Compound Bitwise XOR Operator
Learn how ^= toggles selected bits using masks for alternating states and flag flipping logic.
Lesson 52: Using ++ Increment Operator
Learn how ++ increments values by one, including pre/post increment behavior in loops and counters.
Lesson 53: Using -- Decrement Operator
Learn how -- decrements values by one, including pre/post decrement behavior in loops and countdowns.
Lesson 54: Using << Bitshift Left Operator
Learn how << shifts bits left, multiplies by powers of two, and supports mask-based embedded logic.
Lesson 55: Using >> Bitshift Right Operator
Learn how >> shifts bits right, divides by powers of two, and supports bit-mask style embedded logic.
Lesson 56: Using & Bitwise AND Operator
Learn how & compares bits, filters with masks, and extracts useful flags from packed values.
Lesson 57: Using | Bitwise OR Operator
Learn how | combines bits with masks, sets flags, and supports low-level embedded control.
Lesson 58: Using ^ Bitwise XOR Operator
Learn how ^ compares bit differences, toggles selected bits, and supports efficient state flipping.
Lesson 59: Using ~ Bitwise NOT Operator
Learn how ~ flips every bit, how inversion affects values, and when to use it safely with masks.
