Adding the zeros
You move the decimal the amounts of zeros it has to the right. so if the number is 1.8 x 10= you move the decimal one to the right since it has one zero, then you multiply and get 18.0 its easier with a calculator but its still easy :)
Multiply 4 times 25 to get 100 and then add the two zeros to get 10000
They are 8 times 125 = 1000
1 billion would being as 1,000,000,000 with 9 zeros. So there are 10 zeros in 90 billion: 90,000,000,000.
Yo make it easy, you cover both the zeros and multiply. 3x5=15 30x50=150
102 zeros.
The same as the number of zeros in 10000, that is, 4.
Adding the zeros
add 5 zeros. 1*10000 put a 1 in front and throw 5 zeros on the end. as a general rule any number that ends in zeros, you cann multiply the non zero numbers and add the total number of zeros on the end. 30*20 multiply 3 and 2, get 6 then take the two zeros (one from 30 and one from 20) get 600

1000 multiplied by 60 is equal to 60,000. This can be calculated by multiplying the two numbers together, resulting in the product. Multiplication is a basic arithmetic operation where one number is added to itself a certain number of times, as in this case.
102.

When a natural number is multiplied by 1,000, the product is
Multiply 4 times 25 to get 100 and then add the two zeros to get 10000
yes you can just multiply the 8 and the 5 then add all the zeros you have in the 800 to your answer. EX. 8x5=45 <-- your answer then add the 2 zeros your final answer is 4500
