Simplify (7 + 5) + 4 . 13 - 2
To simplify the expression (7 + 5) + 4 . 13 - 2, we first perform the operations inside the parentheses:
7 + 5 = 12
Next, we multiply 4 and 13:
4 . 13 = 52
Finally, we subtract 2 from 52:
52 - 2 = 50
Therefore, (7 + 5) + 4 . 13 - 2 simplifies to 50.
Step 1: Start by simplifying within the parentheses: (7 + 5) = 12.
Step 2: Rewrite the expression: 12 + 4 . 13 - 2.
Step 3: Next, perform the multiplication: 4 . 13 = 52.
Step 4: Now, rewrite the expression with the multiplication result: 12 + 52 - 2.
Step 5: Lastly, perform the addition and subtraction from left to right: 12 + 52 = 64; 64 - 2 = 62.
Therefore, (7 + 5) + 4 . 13 - 2 simplifies to 62.
To simplify the given expression (7 + 5) + 4 × 13 - 2, follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).
Step 1: 7 + 5 = 12
Step 2: 12 + 4 × 13 - 2
Now, let's calculate the multiplication first:
Step 3: 4 × 13 = 52
The expression now becomes: 12 + 52 - 2
Step 4: Perform the addition: 12 + 52 = 64
Step 5: 64 - 2 = 62
Therefore, the simplified form of (7 + 5) + 4 × 13 - 2 is 62.
