9 x 111 = 999 To simplify the sum, think of it as making 99. 9 x 11 = 99 Then multiply the answer (99) and 11 by ten. That is your answer
99 x 10 - 99 x 9 = 99(1 x 10 - 1 x 9) = 99(10 - 9) = 99(1) =99
To solve this expression, we first need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). First, we perform the multiplication: -999 x 999 = -998,001. Then, we subtract 998,001 from 999,999 to get 1,998. Finally, we divide 1,998 by 999 to get 2.

9 x 111 = 999 To simplify the sum, think of it as making 99. 9 x 11 = 99 Then multiply the answer (99) and 11 by ten. That is your answer
999 x 99 = 98901
99 = 2 100 to 999 = 900 x 3 = 2700 1000 to 1999 = 1000 x 4 = 4000 2000 to 2999 = 1000 x 4 = 4000 3000 = 4 10,706
Easier way than what?I presume you mean long multiplication of 999 by 999, adding 998 and adding 1.One way:999 = 1000 - 1 ⇒ 999 x 999 + 998 + 1 = (1000 - 1) x (1000 - 1) + 998 + 1= 10002 - 2 x 1000 + 1 + 998 + 1= 1000000 - 2 x 1000 + 1000= 1000000 - 1000= 999000Another way:998 + 1 = 999 ⇒ 999 x 999 + 998 + 1 = 999 x 999 + 999= 999 x (999 + 1)= 999 x 1000= 999000
Assuming you mean -2.54545454... x = -2.545454.... x+2 = -0.545454... 100(x+2) = -54.54545454 100(x+2) - (x+2) = 99(x+2) = -54.0000000... x+2 = -54/99 x = -252/99 x = -28/11 or assuming that you mean -2.54254254254... x = -2.54254254... 1000x = -2542.54254... 999x = -2540.00000000... x = -2540/999
x+33=999 x=999-33=966
