What is 76.58 plus 24.3 equallys to what? explain how you added and got your answer

I just added the two numbers and got the number 100.88

The 24.3 translates to 24.30, to match the two decimals of 76.58, then you align them
24.30
76.58
Add the column on the very right: 0 + 8 = 8 ; then the one on the left 3 + 5 = 8; then the next one 4 + 6 = 10; and the one at the very left 2 + 7 = 9 but we add the 1 of the last 10, and leave the 0 on the place, so it's 10
24.30
76.58

100.88
You bring the point down two numbers from right to left, like in the numbers we are adding
