Question

3. Solve: 5 x 4+ (1+1) + 5 = *
Your answer

Answer 1

27

Explanation:

We can solve by using order of operations (PEMDAS), which shows us the order in which we're supposed to perform mathematical operations:

• Parentheses,

• Exponents,

• Multiplication/Division

The / comes from the fact that you do these operations from left to right as multiplication and division have the same level of priority in an equation/operation.

• and Addition/Subtraction.

Like multiplication/division, the / comes from the fact that you do these operations from left to right as addition and subtraction also have the same level of priority in an equation/operation.

Step 1: Simplify inside the parentheses:

5 * 4 + (1 + 1) + 5

5 * 4 + 2 + 5

Step 2: Multiply 5 and 4:

20 + 2 + 5

Step 3: Add 20 and 2:

22 + 5

Step 4: Add 22 and 5 to get your answer:

27

Thus, 5 *4 + (1 + 1) + 5 = 27
