Answer 1

add 12 and a number : 12 + c

Subtract a number from 12 : 12 - c

Divide a number by 12: c over 12

Multiply 12 by a number: 12c

Explanation:

Add 12 and a number:

Let c = any number then the statement "add 12 and a number" will be: 12 + c

Similarly,

As a number has to be subtracted from 12. Subtracting a number from 12 will be: 12 -c

The number has to be divided by 12 so the number will be the numerator and 12 will be the denominator.

Multiplication simply means 12*c OR 12c
