Question 1

If A=@, E=#, G=5, M=0, then 'GAME' is coded as?
Applying symbol substitution: G→5 → A→@ → M→0 → E→# = 5@0#
substitution, basic

Question 2

If +=$, -=*, *=^, /=~, then evaluate: 7 ~ 11 * 1
Decode symbols: 7 ~ 11 * 1 → 7 / 11 - 1 = -1
arithmetic, operations

Question 3

If Layer 1: Letters → position numbers (A=1, B=2...), Layer 2: Numbers → symbols (1=@,2=#,3=$,4=%,5=&,6=*,7=+,8==,9=!,0=?), then code 'COPY'
Layer 1: COPY → C=3, O=15, P=16, Y=25 = 3151625
Layer 2: 3151625 → $@&@*#&
multilayer, complex

Question 4

If A=@, E=#, R=+, T==, W=~, then 'WATER' is coded as?
Applying symbol substitution: W→~ → A→@ → T→= → E→# → R→+ = ~@=#+
substitution, basic

Question 5

If @=B, #=R, $=A, ... then decode: '@#$%&'
Reverse mapping: @#$%& → BRAIN = BRAIN
reverse, decoding

Question 6

If Layer 1: Vowels=@, Consonants=#, Layer 2: @=1, #=2, then code 'COPY'
Layer 1: COPY → #@##
Layer 2: #@## → 2122
multilayer, complex

Question 7

If @=S, #=P, $=A, ... then decode: '@#$%&'
Reverse mapping: @#$%& → SPACE = SPACE
reverse, decoding

Question 8

If consonants at even positions = #, odd positions = *, vowels remain same, then 'PROGRAM' = ?
Consonants at positions: P(pos1→*), R(pos2→#), O, G(pos4→#), R(pos5→*), A, M(pos7→*) = #*O*#A#
conditional, rules

Question 9

If E=#, I=$, C=2, D=3, then 'DICE' is coded as?
Applying symbol substitution: D→3 → I→$ → C→2 → E→# = 3$2#
substitution, basic

Question 10

If Layer 1: Letters → position numbers (A=1, B=2...), Layer 2: Numbers → symbols (1=@,2=#,3=$,4=%,5=&,6=*,7=+,8==,9=!,0=?), then code 'LOAD'
Layer 1: LOAD → L=12, O=15, A=1, D=4 = 121514
Layer 2: 121514 → @#@&@%
multilayer, complex

Question 11

If consonants at even positions = #, odd positions = *, vowels remain same, then 'HARDWARE' = ?
Consonants at positions: H(pos1→*), A, R(pos3→*), D(pos4→#), W(pos5→*), A, R(pos7→*), E = #A#*#A#E
conditional, rules

Question 12

If letters at even positions (1-based) = @, odd positions = #, then 'ALGORITHM' = ?
Alternating pattern: positions 1,3,5,7... = @, positions 2,4,6... = # → @#@#@#@#@
pattern, position

Question 13

If +=^, -=*, *=$, /=&, then evaluate: 9 ^ 8 $ 1
Decode symbols: 9 ^ 8 $ 1 → 9 + 8 * 1 = 17
arithmetic, operations

Question 14

If +=%, -=#, *=@, /=^, then evaluate: 1 # 2 ^ 1
Decode symbols: 1 # 2 ^ 1 → 1 - 2 / 1 = -1
arithmetic, operations

Question 15

If @=M, #=O, $=U, ... then decode: '@#$%&'
Reverse mapping: @#$%& → MOUSE = MOUSE
reverse, decoding

Question 16

If Layer 1: Vowels=@, Consonants=#, Layer 2: @=1, #=2, then code 'LOAD'
Layer 1: LOAD → #@@#
Layer 2: #@@# → 2112
multilayer, complex

Question 17

Using the symbol matrix: F → ! | H → # | D → @ | B → * | A → & Code the word: 'DAH'
Using matrix: D→@ → A→& → H→# = @&#
matrix, mapping

Question 18

Using the symbol matrix: H → = | G → $ | D → ! | C → @ | E → & Code the word: 'HGCDG'
Using matrix: H→= → G→$ → C→@ → D→! → G→$ = =$@!$
matrix, mapping

Question 19

If @=C, #=L, $=O, ... then decode: '@#$%&'
Reverse mapping: @#$%& → CLOUD = CLOUD
reverse, decoding

Question 20

If Layer 1: Letters → position numbers (A=1, B=2...), Layer 2: Numbers → symbols (1=@,2=#,3=$,4=%,5=&,6=*,7=+,8==,9=!,0=?), then code 'SAVE'
Layer 1: SAVE → S=19, A=1, V=22, E=5 = 191225
Layer 2: 191225 → @!@##&
multilayer, complex
