Question

65 - 5 x 7 + (8 x 4 - 2 - 1) = ?

• A. 75
• B. 45
• C. 70
• D. 59

Answer 1

Answer:

D. 59

To solve this expression, we use the BODMAS / PEMDAS rule.

• B — Brackets first

• O — Orders (Exponents)

• D — Division

• M — Multiplication

• A — Addition

• S — Subtraction

---

$65 - 5 \times 7 + (8 \times 4 - 2 - 1)$

---

Step 1: Solve the Brackets $(\dots)$

Inside the brackets, follow the order of multiplication before subtraction.

• Multiply: $8 \times 4 = 32$

• Subtract: $32 - 2 = 30$

• Subtract remaining: $30 - 1 = \mathbf{29}$

The expression now becomes:
$65 - 5 \times 7 + 29$

Step 2: Perform Multiplication $(\times)$

Next, multiply the numbers outside the brackets.

• Multiply: $5 \times 7 = \mathbf{35}$

The expression now becomes:
$65 - 35 + 29$

Step 3: Perform Addition and Subtraction (Left to Right)

Now, perform the remaining operations from left to right.

• Subtract: $65 - 35 = 30$

• Add: $30 + 29 = \mathbf{59}$
