12 × 4:3 × 21:5 = 8:5 + 8:5 × 10:7 = 12:7 × 14:9-9:2=
12 × 4 / 3 × 21 / 5 = 45 / 21 = 15 / 7 (15 / 7)
5 / 8 + 5 / 8 × 7 / 10 = 17 / 16 (17 / 16)
7 / 12 × 9 / 14-2 / 9 = 11 / 72 (11 / 72)

(2 minus 2 / 3) multiply (3 minus 3 / 4) multiply (4 minus 4 / 5) multiply (9 minus 9 / 10)
Simple calculation
This is regular. The general formula of each term is an = (n + 1) & # (n + 2) expand this to be: two minus two thirds = 4 / 3, three minus three quarters = 9 / 4 Write these terms, multiply them, and simplify them (because the square root of the molecule of the latter term from the second term is the molecule of the former term) to get: 4 × 3 × 4 × 5

How much is 0 times 0?
It's not zero
Is 0 times 0 equal to 0?
If 0 is multiplied by any number that is not 0, then 0 will get 0. There is no definition for 0 multiplied by 0. If 0 is multiplied by a non-zero number, then 0 divided by the non-zero number equals 0. This is an inverse operation of the previous operation, and 0 divided by 0 is meaningless. If 0 is multiplied by 0, then there is no inverse operation?
