Collecting
shells on the beach is definitely one of the activities you love. This morning
you have to collect shellfish number 29 seed, and this afternoon you collect
again 44 seeds. How many shells that you collect all of them? to solve this
problem, you would add 29 + 44.
------- Thus Trick ------
Anytime
if you add a number to the unit number 9, add 1 point 9 is (but do only in your
mind). So numbers like 29 would be 30. Then subtract 1 on the following numbers
so that the number 44 will become 43. Then, add up the new numbers that you
have got, and you'll get results. Let us use this moment to determine the
number of shells that had been turned away you pick up earlier!
Problem:
29 + 44
Always
Remember ...!! Multiples of the number 10 (such as 20, 30 and so on) is always
easier summed than not berkelipatan 10. Kick-started by adding the number 1 on
numbers ending denngan unit number 9 to be a multiple number 10. If you add up
the numbers with one number unit 8, add 2 to be multiples of 10. Then, the
second number minus 2. Then add up the new numbers. You will immediately get
results. For example, 48 + 6 becomes (48 + 2) + (26-2), or 50 + 24 outcome 74.
