To add 435 and 5 step by step, you can use long addition:
435
+ 5
-----
Start by adding the digits in the rightmost column (the ones place):
435
+ 5
-----
0
Since 5 + 5 equals 10, write down 0 in the result, and take 1 carry to the next column(tens place).
Now, move to the next column (the tens place) and add the digits there:
(1)--carry
435
+ 5
-----
40
3 + 1(carry) equals 4, so write down 4 in the result under the tens place.
Finally, move to the hundreds place:
435
+ 5
-----
440
Since there are no more digits to add, you just write down 4 as it is in hundreds place and thus you have your final result:
435 + 5 = 440
So, 435 + 5 equals 440.
