Question

Simplify -3(-2-3+6)-(-5(-2)+3(-2-4))

Answer 1

what did you get?
these are getting tougher

Answer 2

btw i am wondering, are the instructions really "simplify"? it should be "compute"

Answer 3

−3(−2−3+6)−(−5(−2)+3(−2−4))

−3⋅1−(5⋅2+3(−6))

Thats what i got so far. and yeah they say simplify.

Answer 4

First you have *-3 to all:
-3(-2-3+6) = -3 . -2 -3.-3-3.6

Answer 5

k looks good so far

Answer 6

i dont know what to do now?

Answer 7

−3⋅1−(5⋅2+3(−6))

Answer 8

\(-3\times 1=-3\)

Answer 9

so now it will be -3−(5⋅2+3(−6))

Answer 10

\[-3-(5\times 2+3\times (-6))\]

Answer 11

then \(5\times 2=10\) and \(3\times -6=-18\)

Answer 12

(+).(+)=+
(-).(-)=+
( _ ).(+)=(-)
Remember it !

Answer 13

\[-3-(10-18)\]

Answer 14

Ok what does that look like?

Answer 15

ok

Answer 16

two more steps
\[10-18=-8\]
\[-3-(-8)\]

Answer 17

one more step
\[-3-(-8)=-3+8\]

Answer 18

and the final answer is 5?

Answer 21

Simplify the following:
-(-5 (-2)+3 (-2-4))-3 (-2-3+6)
Group the negative terms in -2-4 together and factor out the minus sign.
-2-4 = -(2+4):
-3 (-2-3+6)-(-5 (-2)+3×-(2+4))
Evaluate 2+4.
2+4 = 6:
-(-5 (-2)+3 (-6))-3 (-2-3+6)
Multiply -5 and -2 together.
-5 (-2) = 10:
-(10-6×3)-3 (-2-3+6)
Multiply 3 and -6 together.
3 (-6) = -18:
-3 (-2-3+6)-(10+-18)
Group the negative terms in -2-3+6 together and factor out the minus sign.
-2-3+6 = 6-(2+3):
-(10-18)-36-(2+3)
Evaluate 2+3.
2+3 = 5:
-(10-18)-3 (6-5)
Subtract 5 from 6.
6-5 = 1:
-(10-18)-31
Factor out a negative sign in 10-18 in order to subtract.
10-18 = -(18-10):
-3×1--(18-10)
Subtract 10 from 18.
| 1 | 8
- | 1 | 0
| 0 | 8:
-(-8)-3×1
Multiply all instances of -1 in -(-8).
(-1)^2 = 1:
8-3×1
Multiply -3 and 1 together.
-3×1 = -3:
-3+8
Subtract 3 from 8.
8-3 = 5:
