Words for operations is one of the basic topic in algebra. Students who would like to learn solving word problems in math must study this basic stuff.
This will help us to write numerical expression for word problems or practical problems.
(+) 

() 

(x) 

Note:
Twice means multiply by 2 and thrice means multiply by 3
÷ 

When we have the above words in the question, we can replace it by the corresponding mathematical symbols.
Example 1 :
Write a numerical expression for the quotient of 20 and 5.
Solution :
In the given question we have the word quotient, the corresponding symbol for the word "quotient" is "÷".
Hence, the numerical expression for the given question is
20 ÷ 5
Example 2 :
Write a numerical expression for the difference between 42 and 19
Solution :
In the given question we have the word difference between, the corresponding symbol for the word "difference between " is "".
Hence, the numerical expression for the given question is
42  19
Example 3 :
Write a numerical expression for the product of 7 and 12
Solution :
In the given question we have the word product of, the corresponding symbol for the word "product of " is "x".
Hence, the numerical expression for the given question is
7 x 12
Example 4 :
Write a numerical expression for 30 more than 20
Solution :
In the given question we have the word more than, the corresponding symbol for the word "more than " is "+".
Hence, the numerical expression for the given question is
30 + 20
Example 5 :
Write a numerical expression for 100 decreased by 77
Solution :
In the given question we have the word decreased by, the corresponding symbol for the word "decreased by" is "".
Hence, the numerical expression for the given question is
100  77
