third you will back the 4 in 34 become a 0 and drop down the zero in your answer under the four under the line..
fourth you will ha vet to multiply 6 x 3 = 18 put the 8 beside the zero and put the one one the very top of the five.
fifth you multiply 5 x 3= 15 and write do the 15 beside the zero and you should get..........
1224+ 1,5801,804There are 9 1-digit numbers and 16-2 digit numbers. So a 5 digit combination is obtained as:Five 1-digit numbers and no 2-digit numbers: 126 combinationsThree 1-digit numbers and one 2-digit number: 1344 combinationsOne 1-digit numbers and two 2-digit numbers: 1080 combinationsThat makes a total of 2550 combinations. This scheme does not differentiate between {13, 24, 5} and {1, 2, 3, 4, 5}. Adjusting for that would complicate the calculation considerably and reduce the number of combinations.
Any number with 2 numbers in it is a 2. Example: 95 They are numbers 10 - 99.

By using the 3 digits of a number we can form 3 different two digit numbers. 3C2 = 3!/[(3 - 2)!2!] = 3!/(1!2!) = (3 x 2!)/2! = 3
If you want 4-digit numbers, there are 24 of them.
A 3 or 4 digit number.

What is multiplying 2-Digit by 2-Digit numbers

Multiplication in general is important; not just 2-digit numbers.
Multiplying a 1-digit number by a 2-digit number involves scaling the smaller number, which can often be done using simpler methods like repeated addition or distributing the multiplication over the tens and units. In contrast, multiplying two 2-digit numbers requires more complex strategies, such as the lattice method or long multiplication, as it involves handling both tens and units from both numbers. However, both processes fundamentally involve the same principles of multiplication, such as combining partial products to reach a final answer. The key difference lies in the complexity and the number of parts involved in the calculation.
If multiplying 3 digit numbers with 2 digit numbers. For example; 345 x 92= First you will start with 2 by multiplying it by 5 then carry the 1 above the 4 then multiply the "2" with 4 then add the number on-top of the 4 which is 1 and it will give you 9. 4 x 2= 8+1=9. Then times the 2 by 3 which is 6. That is not your answer, yet. 690 plus the amount you get by multiplying 9 by every number, 5 then carry the number, 4 times 9, plus the number above it, then carry the 3 on top of the 3. Then add your total to 690 or what ever your equation is.

The ones digit in the product from multiplying the 305 prime numbers less than 2012 is 0 because the ones digit becomes 0 after 2 and 5 have been multiplied and remains unchanged after more prime numbers are multiplied.
There are 28706 such combinations. 5456 of these comprise three 2-digit numbers, 19008 comprise two 2-digit numbers and two 1-digit numbers, 4158 comprise one 2-digit number and four 1-digit numbers and 84 comprise six 1-digit numbers.
You have 4 options for the first digit, 3 for the second, 2 for the third. Multiplying all this you get 4 x 3 x 2 = 24 options.
