Question

Evaluate the expression 3∗4%6+4 *5 (a) 20 (b) 26 (c) 12 (d) 32

Answer 1

The expression 3*4%6+4*5 is evaluated according to order of operations PEMDAS. The multiplication operations are performed first, followed by the modulo operation, and finally the addition operation. The final result is 20.

Step-by-step explanation:

The question asks to evaluate the expression 3∗4%6+4∗5. First, lets break it down according to order of operations which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), also known as PEMDAS. As there are no parentheses or exponents, we will perform multiplication first.

• First, multiply 3 by 4 which equals 12.
• Then, compute 12 modulo 6 (% is the symbol for modulo; the modulo operation finds the remainder after division of one number by another). The remainder of 12 divided by 6 is 0.
• After that, multiply 4 by 5 which equals 20.
• Lastly, add the result of 12%6 with the product of 4*5 to get 0 + 20.

So, the final answer is 20 (option a).
