Step-by-step explanation:

Answer 2

Why the calculation is being done to show???!!!

Let me use a mathematical concept to show that 7 + 3 × 5 × 7 is an even number, without calculation.

According to BODMAS, multiplication occurs first and then addition.

So 3, 5, 7 are multiplied at first and 7 is added then.

Okay, first is 3 × 5 × 7.

The product of odd numbers is always odd.

∴ 3 × 5 × 7 gives an odd number.

Next is adding 7 to 3 × 5 × 7.

We got that 3 × 5 × 7 is odd.

The sum of odd numbers is always even.

∴ 7 added to 3 × 5 × 7 is an even number.

∴ 7 + 3 × 5 × 7 is an even number.

Hence showed!

Hope this concept may be helpful.

Thank you. Have a nice day. :-)
