2[3(10)-(-3)] is this ur quastion

OpenStudy (dayakar):

first multiply 3*10 =30 _(-3) = +3 now it becomes like this 2[30+3]

OpenStudy (dayakar):

=2*33 =66

OpenStudy (dayakar):

MsBrains (ms-brains):

Wait, why did -3 become positive?

MsBrains (ms-brains):

@dayakar

OpenStudy (johan14th):

-3 became positive because the minus sign between 10 and 3 and the negative sign in front of 3 cancel each other out and make a positive.
