31 x 10 = 310
10 with 1 remaining 31 - 1 = 30 = 3 x 10
8 times with a remainder of 10
31 billion can be expressed in scientific notation as (3.1 \times 10^{10}). This is achieved by moving the decimal point in 31 to the right, which shifts the exponent of 10 to 10, as there are ten places from 3.1 to 31 billion.
2, remainder 10
Imagine instead that your equation is (124/10) * (31/10), or, all things being commutative in multiplication, (124 * 31) * (1/10 * 1/10) = (124 * 31) * (1/100) = (124 * 31) / 100. Multiply the first term, and you get 3844. Once you divide from there, you get 38.44.
3 goes into 31 10 times with remainder 1.
it is 2,790
10 with 1 remaining 31 - 1 = 30 = 3 x 10
31 x 10 = 310 Therefore there is only a single zero.
3 squared times 2 times 10 32*2*10 = 9*2*10 = 180
