• Example: LDAA #55 → Load A with 55

• Example: ADDA $20 → A = A + value at memory address $20

# → Immediate Value

• Means: “Use this number directly, not from memory.”
• Example: LDAA #55 → A = 55

$ → Hexadecimal Number

• Means: “The following number is in hexadecimal.”
• Example: LDAA $20 → A = value stored at memory[0x20]

@ → Indirect Addressing (pointer)

• Means: “Use the memory location stored in a register or memory cell.”
• Example: LDAA @X → A = memory[X]
