Step-by-step explanation:
We have to apply bodmas in it.
B (bracket)
O (of or open)
D (division)
M (multiplication)
A (addition)
S (subtraction)
IN THIS SUM, THERE IS NOT DIVISION SO WE WILL FIRST DO MULTIPLICATION.
999×989×989
=977142879
999999-2×977142879+989
NOW, WE WILL ADD 989 INTO 999999, BECAUSE THERE IS A SIGN OF POSITIVE AT THE FRONT OF BOTH THE NUMBERS, SO WE CAN NOW ADD THEM.
999999+989
=1000988
NOW, THE EQUATION IS
1000988-2×977142879
1000988-1954285758
=
