Just add a zero behind the number. (8 x 10 = 80)
You add two zeros at the end of the answer 80*90=7200
99
Use workmat5 and hundereds,tens,and ones
use the tens place to multiply by 2, then use the number to subtract the ones place.The answer can be divided by 7, if not it will be 0.use 490 as an example.9x2=18.18-4=14.14 divided by 7 is 2. so 49 can be divide by 7
15 638 can be made with 1 ten, 5 ones, 6 hundreds, 3 tens, and 8 ones; 1 ten, 8 ones, 6 hundreds, 3 tens, and 5 ones; or 6 ones, 5 hundreds, 3 tens, 8 ones, and 1 ten.
To represent decimals for ones and tens, you place the decimal point to indicate the whole number and fractional parts. For example, the number 12.5 has 12 as the whole part (ones and tens) and 0.5 as the decimal part. If you want to express a value in the tens place, you can use numbers like 20.3, where 20 represents two tens and 0.3 indicates three-tenths. Always ensure that the number to the left of the decimal point reflects the correct place value for ones and tens.
There is no difference.
You can make one. But, since you can multiply ones and tens separately, and add (i.e., use the common multiplication algorithm), it really isn't necessary to have a multiplication table beyond the range from 0x0 to 9x9.
Is that you look at the 1 and it is on the hundreds place and you look at the 6 and its on the tens place and the 5 is in the ones placed a to 0.98 is that the 9 is in the tens place and the 8 is in the ones place
When you multiply a two digit number by another, you use the distributive property because you basically are taking the tens digits times both the other tens digit and the ones digit, then the ones digit times both the other tens and other ones digits. That sounds confusing, I know, but I'll explain. If you're taking 12 times 25, you are basically doing the problem (10+2) x (20+5). You take ten times twenty, then ten times five, then two times twenty, then two times five, and add them all together.
To multiply by a two-digit number, you can use the distributive property. Break the two-digit number into its tens and ones components. For example, to multiply 34 by 12, you can calculate (30 + 4) × (10 + 2). Then, multiply each part: 30 × 10, 30 × 2, 4 × 10, and 4 × 2, and finally add all the results together to get the final product.
In International Indian System we use ones,tens,hundreds,thousands and then lakhs and crores.
