weird but ok

Let's first simplify the expression in the parentheses using the order of operations (PEMDAS):

1+2+3+4+5+6+7+8+9+10-1-2-3-4-5-6-7-8-9-10x1x2x3x4x5x6x7x8x9x10÷1÷2÷3÷4÷5÷6÷7÷8÷9÷10

= 55 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) ÷ (1 ÷ 2 ÷ 3 ÷ 4 ÷ 5 ÷ 6 ÷ 7 ÷ 8 ÷ 9 ÷ 10)

Next, let's evaluate the expression in the parentheses. We can simplify by dividing the numerator and denominator separately:

10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 ÷ (1 ÷ 2 ÷ 3 ÷ 4 ÷ 5 ÷ 6 ÷ 7 ÷ 8 ÷ 9 ÷ 10) = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 ÷ (3628800 ÷ 362880)

= 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 x 362880 ÷ 3628800

= 362880

Substituting this value back into the original expression, we get:

55 - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 362880

= -362773

Therefore, the value of the expression is -362773.

Answer:

129,600

Step-by-step explanation:

Macacmcel ung addition and subtraction part, the multiplication part is 362 880 over the division part which is 2.8, thus resulting 129,600
