To solve the expression $83 + 238 ÷ 17 - 64$, we must follow the order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
First, calculate the division part of the expression:
$238 \div 17 = 14$
Substitute the result back into the expression and perform the addition:
$83 + 14 - 64$
$83 + 14 = 97$
Finally, perform the subtraction:
$97 - 64 = 33$
Thus, the value of the expression $83 + 238 ÷ 17 - 64$ is 33.
Identify the number that will replace the question mark in the second equation based on the relationship represented in the first equation.

What value should come in the place of question mark (?) in the following equation?
$(0.008\div?) + (0.006 \div 0.03) + (0.008 \div 0.04) =0.5$
If 'I' stands for '+', 'J' stands for 'x', 'K' stands for '÷', and 'L' stands for '-', then what will come in place of the question mark (?) in the following equation?
6 K 2 J 4 L 3 I 9 = ?
If 'A' stands for '$\div $', 'B' stands for 'x', 'C' stands for '+' and 'D' stands for '-', then what will come in place of the question mark (?) in the following equation?
33 A 3 C 4 B 2 D 4 A 2 = ?
