The document contains a quiz on addressing modes with 8 questions that calculate the effective address and operand value for different load instructions. Each question provides the load instruction, identifies the addressing mode, and gives the effective address and value loaded into the accumulator. For example, question 1 uses loadAx, ([500]) with an effective address of 800 and loads the value 300 into AX.

2. Find out the effectiveaddressof operandand
accumulator & operandvalueby addressingmodes
and also identify their modes.
1.LoadAx , ( [500] )
Solution:
EffectiveAddress = 800
Operand = 300
AX 300
2.LoadAx, BX
Solution:
EffectiveAddress = Nil
Operand = 702
AX 702
3.LoadAx, ( DX )
Solution:
EffectiveAddress = 400
Operand = 700
AX 700
4.LoadAx, ( ( [500] ) )
Solution:
EffectiveAddress = 300
Operand = 950

3. AX 950
5.LoadAX,DX
Solution:
EffectiveAddress = Nil
Operand = 400
AX 400
6.LoadAX, ((DX))
Solution:
EffectiveAddress = 700
Operand = 399
AX 399
7.LoadAX, (((DX)))
Solution:
EffectiveAddress = 399
Operand = 600
AX 600
8.Loadax, ((((dx))))
Solution:
EffectiveAddress = 600
Operand = 900
AX 900
