The End of the Line

No need even mental calculations :3

finding the last digit of the product of 1234 x 4321. we just need to multiply the last digit of the first expression to the second. 4 x 1= 4 so the last digit of the product is 4.

1 and 4 are the last digits and by multiplying them we get 4 which is the last digit of the product

In order to get the last digit......
Just multiply last digit as
1234: last digit is 4 and
4321: last digit is 1
Hence,
4*1 = 4
The last digit is 4.

First digit is 5 because 4×2+3×1=11 and 1 will get added to 4×1 Check diagram from aloysius mahendra , look for lower 4 and 3

$(1000+200+30+4) \times (4000+300+20+1)$ expands to give the only contribution to the units as the $4 \times 1$ term

1 x 4 = 4 The last digit is the result of the product of the last digits

How to find last three digits?

If we want the last digit just multiply the last digit of the two numbers. So 4*1=4

1234x4321= the last digit multiplication is 4x1=4

if we multiply last two digit then we find that 4*1=4

1234*4321=533211(4)

Last digits from the two numbers are 4 and 1. 1 multiplied by 4 is equal to 4

$1(4) = 4$

If you do it as a written method, there is no number under four (because for every different unit you need to shift it one space to the left) , so the last digit will always be the product of the last units' unit. Agh too, too easy

1 multiples by 4 is 4

1x2=2 and 1x4=4

Multiply units 4x1=4

All you need to do is multiply the last two digits as these are the ones that will decide the last digit of the product. The question was the last digit of 1234 x 4321, therefore the answer is four as the last digit of each(in their respective order) is 4 x 1. The answer to this is 4.

To get the last digit of the product just multiply the units place of both. 4*1=4

in standard method of multiplying we learned in school is multiply first last digit multiplicand to the last digit of multiplier then add this in diagonal form , so 4x1=4 4 is the last digit

Just multiply their last digit, 1x4

If you multiply last digit of both numbers then you will get 4. i.e., 4*1 = 4

multiply right most digit only. In multiplication The digits to the left will not affect the outcome. Therefore 4x1=4.

why not use calculator :D

Just multiply the last 2 digits of each number

All you have to do is multiply the last two digits of each number, since a zero is added with each successive multiplication

1 and 4 are the last digits and by multiplying them we get 4 which is the last digit

4 X 1....for the last digit...

how I collect my dollars

4 lololol

(1000 + 200 + 30 + 4)(4000 + 300 + 20 + 1) The last digit is the product of the last terms (4 x 1) which equals 4.

If you don't know how to solve this. I can't help you.

when multiplying ( 1234 ) by (4321 ) , the whole number (1234 ) is first multiplied by the first digit in ( 4321 ) which results 1234, so the last digit of the product is 4

Finding the last digit is the same as doing the multiplication modulo 10. $1234 \times 4321 \quad \text{mod 10} \\ \cong \ 4 \times 1\quad \text{mod 10} \\ \cong 4 \quad \text{mod 10}$

Only unit digit affect the last digit and 1*4 =4
