First we set up the long multiplication
Next we multiply 1 * 9 which is 9
Next we multiply 1 * 2 which is 2
Next we multiply 3 * 9 = 27 and since 27 is two-digit, we have to carry the first digit 2 to the next column
Next we multiply 3 * 2 which is 6 and then we carry digit of 2, which is 8
And lastly we add 870 + 29 and we get 899.
Next we multiply 1 * 9 which is 9

The mistake Lori made when multiplying is that she didn't regroup the 2 in the tens column.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements.
What is simplification?
The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
In the given question, Lori solved this multiplication problem. 29 × 31 = 699 However, the mistake Lori made when multiplying is that she didn't regroup the 2 in the tens column.
so the correct multifunction is
31
x 29
--------
279
+62x
---------
899
Thus, the mistake Lori made when multiplying is that she didn't regroup the 2 in the tens column.
