Answer 1

To simplify the expression (1.9−0.3)÷8+4×3 using the order of operations (also known as PEMDAS/BODMAS - Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)), we will follow these steps:

1. **Calculate inside the parentheses:**
\[
1.9 - 0.3 = 1.6
\]

2. **Rewrite the expression:**
\[
(1.9−0.3)÷8+4×3 \rightarrow 1.6 ÷ 8 + 4 × 3
\]

3. **Perform the division and multiplication from left to right:**
- First, calculate \(1.6 ÷ 8\):
\[
1.6 ÷ 8 = 0.2
\]

- Next, calculate \(4 × 3\):
\[
4 × 3 = 12
\]

4. **Rewrite the expression with the calculated values:**
\[
0.2 + 12
\]

5. **Perform the final addition:**
\[
0.2 + 12 = 12.2
\]

Thus, the simplified expression is:
\[
\boxed{12.2}
\]
