Explanation

Let us convert the given word expression into a numerical format by deriving each term and its operation.

The operation of multiplication or 'x' in words is 'times'.

Eight times of a number b is denoted by 8xb = 8b.

Ten times of a number c is denoted by 10xc = 10c.

The operation of subtraction is denoted by ' - '.

Since we are subtracting eight times the number b from ten times the number c, we will write the term 10c first and then place the operation sign (of subtraction), which is followed by the next term 10c.

Hence, the required expression is = 10c- 8b.
