Let's simplify each expression step by step:
-
For the expression \( 18 - 42 + 5.2 \): \[ 18 - 42 = -24 \ -24 + 5.2 = -18.8 \ \text{(This value is not among the provided options)} \]
-
For the expression \( 92 + 9.7 - 3 \): \[ 92 + 9.7 = 101.7 \ 101.7 - 3 = 98.7 \ \text{(This value is not among the provided options)} \]
-
For the expression \( 52 - 4 + 7.3 \): \[ 52 - 4 = 48 \ 48 + 7.3 = 55.3 \ \text{(This value is not among the provided options)} \]
It looks like none of these expressions yield a simplified result that matches the values you've provided (1, 2, 12, 24, 42, 106). Please check the expressions or options for any errors. If you have specific results you would like me to analyze further, please let me know!
