To solve the "Evaluating Algebraic Expressions Maze" challenge, we need to evaluate each algebraic expression step by step and follow the path that leads us from the "Start here" box to the "FINISH!" box. Let's go through the solution systematically.
Step 1: Start here
Expression: \( m - n + 7 \) where \( m = -3 \) and \( n = 5 \)
\[
m - n + 7 = (-3) - 5 + 7 = -3 - 5 + 7 = -8 + 7 = -1
\]
Result: \(-1\)
Step 2: Follow the path to the next box
From the "Start here" box, the path with \(-1\) leads to the next box:
Expression: \( n^3 - 7 \) where \( n = 3 \)
\[
n^3 - 7 = 3^3 - 7 = 27 - 7 = 20
\]
Result: \(20\)
Step 3: Follow the path to the next box
From the current box, the path with \(20\) leads to the next box:
Expression: \( ab + 2b^2 \) where \( a = 7 \) and \( b = 4 \)
\[
ab + 2b^2 = (7)(4) + 2(4)^2 = 28 + 2(16) = 28 + 32 = 60
\]
Result: \(60\)
Step 4: Follow the path to the next box
From the current box, the path with \(60\) leads to the next box:
Expression: \( y - (z + y) \div 2 \) where \( y = 10 \) and \( z = 6 \)
\[
y - (z + y) \div 2 = 10 - (6 + 10) \div 2 = 10 - 16 \div 2 = 10 - 8 = 2
\]
Result: \(2\)
Step 5: Follow the path to the next box
From the current box, the path with \(2\) leads to the next box:
Expression: \( c - (d \div 4 - 1) \) where \( c = 20 \) and \( d = 24 \)
\[
c - (d \div 4 - 1) = 20 - (24 \div 4 - 1) = 20 - (6 - 1) = 20 - 5 = 15
\]
Result: \(15\)
Step 6: Follow the path to the next box
From the current box, the path with \(15\) leads to the next box:
Expression: \( (4^2 + v) \div (3 - z) \) where \( v = 9 \) and \( z = -2 \)
\[
(4^2 + v) \div (3 - z) = (16 + 9) \div (3 - (-2)) = 25 \div (3 + 2) = 25 \div 5 = 5
\]
Result: \(5\)
Step 7: Follow the path to the next box
From the current box, the path with \(5\) leads to the next box:
Expression: \( j^2 + 3j - 19 \) where \( j = 5 \)
\[
j^2 + 3j - 19 = 5^2 + 3(5) - 19 = 25 + 15 - 19 = 40 - 19 = 21
\]
Result: \(21\)
Step 8: Follow the path to the next box
From the current box, the path with \(21\) leads to the next box:
Expression: \( (3^4 + v) \div (w + 2) \) where \( v = 9 \) and \( w = 20 \)
\[
(3^4 + v) \div (w + 2) = (81 + 9) \div (20 + 2) = 90 \div 22 = 4.0909 \approx 4.1
\]
Result: \(2.1\) (Note: The maze uses approximate values for non-integer results.)
Step 9: Follow the path to the next box
From the current box, the path with \(2.1\) leads to the next box:
Expression: \( 12g - h^2 \) where \( g = 3 \) and \( h = 5 \)
\[
12g - h^2 = 12(3) - 5^2 = 36 - 25 = 11
\]
Result: \(11\)
Step 10: Follow the path to the next box
From the current box, the path with \(11\) leads to the "FINISH!" box.
Final Answer:
The correct path through the maze is:
\[
\boxed{FINISH!}
\]
