42-13+(12x2)=

(12*2)=24

42-13=29

29+24 = 53

Multiply 104 by 102

15-24 divided by 2.2

To solve this mathematical expression, you need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Here's how you can approach it step by step:

Step 1: Start with the parentheses (if any). In this case, there are no parentheses.

Step 2: Next, perform any multiplication or division. In this case, we have 12 multiplied by 2, which equals 24.

Step 3: Now, we have 42 - 13 + 24 left.

Step 4: Lastly, perform any addition or subtraction from left to right.

Start by subtracting 13 from 42: 42 - 13 = 29.

Finally, add 29 to 24: 29 + 24 = 53.

Therefore, 42 - 13 + (12 x 2) equals 53.
