You were almost there Kayla. Let me just modify your answer.
You multiply 98 x 81. First 98 x 1 = 98. So it is 98. Now do 98 x 80 which is 7840. Now add 7840 + 98 = 7938.
Answer: 7938
It should have been multiplied by 80 rather than 8
You had 98*81
98*81 = 98*(1 + 80) = 98*1 + 98*80 = 98 + 7840 = 7938
