Answer 3

Sure, I can help you calculate these products vertically. Here's the step-by-step process:

kotlinCopy code
   80
x  15
_____
   00   (80 multiplied by 5)
+ 400   (80 multiplied by 10, shifted one position to the left)
_____
= 1200  (The final result of 80 multiplied by 15)

kotlinCopy code
   90
x  16
_____
   00   (90 multiplied by 6)
+ 900   (90 multiplied by 10, shifted one position to the left)
_____
= 1440  (The final result of 90 multiplied by 16)

cssCopy code
   14
x  17
_____
   28   (14 multiplied by 7, shifted one position to the left)
+ 210   (14 multiplied by 10, shifted two positions to the left)
_____
= 238   (The final result of 14 multiplied by 17)

cssCopy code
   17
x  19
_____
   63   (17 multiplied by 3, shifted one position to the left)
+ 170   (17 multiplied by 9, shifted two positions to the left)
_____
= 323   (The final result of 17 multiplied by 19)

So, the products are:

80 * 15 = 1200 90 * 16 = 1440 14 * 17 = 238 17 * 19 = 323
