OBJECTIVE Find sums of four 2-digit numbers.
You can add 4 numbers in different ways.
One way is to add pairs of digits in the
ones column.
1
16
22
31
+ 16
____
85
Add a pair
of digits.
6+2=8
Add the
other pair.
1+6=7
You can add
numbers in any
order. The sum
stays the same.
Then add
these two
sums.
8 + 7 = 15
Then add the digits in the tens column.
So, 16 + 22 + 31 + 16 = 85.
