35 +12=12okthen 12+54=66+17=83+84=167+21=188ans check it nicely it's very easy

Answer 2

Answer: 84+21=21

Step-by-step explanation:

Since we have 35+12=12

So, we get that

Minimum of first digits of both the number will be at tens place and minimum of second digit of both the numbers will be at ones place.

$Min(3,1)\times 10+Min(5,2)\\\\=1\times 10+2\\\\=12$

Again, we have 54+17=14

Using the same pattern above:

$Min(5.1)\times 10+Min(4,7)\\\\=1\times 10+4\\\\=14$

Similarly, for 84+21

we will have

$Min(8,2)\times 10+Min(4,1)\\\\=2\times 10+1\\\\=21$

Hence, 84+21=21
