16times12-672+21=?-211

What will come in place of question mark(?) in the following questions? 16x12 -672+21 = ? -211

16xx12-672-:21=?-211

State true of false. If the statements are correct, then state the property used. 16 times (23-12)=(16 times 23)-(16 times 12)

State true of false. If the statements are correct, then state the property used. 12 times (11+21)=(12 times 11)+(12 times 21)

Verify: (-17) times 21=17 times (-21)

Verify: (-21)times[(-4)+(-6)=[(-21)times(-4)]+[(-21)times(-6)]

Verify: (-21)times[(-4)+(-6)=[(-21)times(-4)]+[(-21)times(-6)]

Find the product: 16times12

If sum_(k=1)^(12)12k^(12)C_(k)^(11)C_(k-1) is equal to (12times21times19times)/(11!)times2^(12)times P then P is
