4 & 5 Digit to 5 Digit Addition Worksheets
How do you stay organized when adding large values? The addition is a simple mathematical technique to learn. It is taught in elementary level grades, and children can easily learn it and solve it in writing. However, doing it mentally can be a bit daunting at times. Mental math is a technique that can be mastered with a lot of practice, but again, small digit numbers are relatively easier to add in mind, as compared to large digit numbers. People often lose track of a sum when they are trying to add large digit values. Keeping composed is the key while adding a large digit number. First of all, you need to take care of adding each digit of the first number to its corresponding digit of the other number. Then, if after adding the two corresponding digits, we get an answer of a doubledigit number, we write the right digit down and carry the left digit to the next column. This is how the addition of large digits can be done in an organized manner.

Good Manners and Math
Sometimes math teachers have to integrate good manners into their lessons. A teacher asked her student, "What is 2Q plus 3Q?" The student replied "5Q." "Correct. Now, what is 5Q plus 5Q?" ""10Q," said the student. "You're welcome" was the response.
