Do you know that it's easy to add from left to right!
The easiest two-digit addition is those who do not carry any numbers. For example:
44 + 35
To solve 44 + 35, first, add 30 then add 5 (35 = 30 + 5). After adding 30, you have a simple problem 74 + 5, which equals 79. We illustrate this as:
44 + 35
(first add 30)
= 74 + 5
(then add 5)
= 79
Let's try another one, which carries a number:
69 + 25
Adding form left to right, we can say that:
69 + 25
(first add 20)
= 89 +5
(then add 5)
= 94
Try this one:
92 + 58
We can say that:
92 + 58
(first, add 50)
= 142 +8
(then add 8)
= 150
