Q. Evaluate the expression.

\newline

1 - 2 + 3

Perform Operations Left to Right: $1 - 2 + 3$ $\newline$ First, perform the operations from left to right, as there are no parentheses or exponents to consider, and addition and subtraction have the same precedence. $\newline$ Subtract $2$ from $1$ . $\newline$ $1 - 2 = -1$
Subtract $2$ from $1$ : Simplify $-1 + 3$ . Add $3$ to $-1$ . $-1 + 3 = 2$
