L.I: To calculate the sum of whole numbers using algorithm.

L.I: Carry numbers to the next column if needed.

Algorithm is a method used in math to add, subtract, and multiply big numbers. To be able to use algorithm you would need to know your place value and basic number knowledge. Like times tables and simple addition or subtraction. To use Algorithm Multiplication, times tables are a key. If you aren’t 100% percent sure with your times tables, your answers my not be accurate.

Multiplication Algorithm, is like the same with addition, but multiplying the numbers. If you are multiplying the ones the first answer goes under the ones column and the rest of the numbers go to the left. If the answer to a multiplication question has 2 digits, you carry over the the tens to the next number. When you move on from multiplying the ones digit to the tens, you add a zero, as a place holder. That is because you aren’t multiply to ones, but the tens. And when you are onto the hundreds column, you add 2 place holders, and so on. When are the columns are complete, you add them together to get the answer to your multiplication equation. For example, to do 143 x 253. You multiply 143 by 3. 3 times 3 is 9. 3 times 4 is 12. So you carry over the 1. And 3 times 1 is 3, and you add the 1 that you carried over, so the answer would be 4. So your answer is 429. But you still have to multiply the tens and hundreds. So you do the same process by add the place holders first.

I enjoyed this activity a lot because I learnt an easier way to multiply large numbers by large numbers. I also enjoyed this because I learnt how to use place holders. Because normally I would just leave a gap.
