How to do a Algebra problem?

Question

can you please solve it and show you work please.

1. 6-2(4+5) +6

2. 5-2 x 3+6(3^2+1)

Answer 1

for number one you will definitly use PEMDAS

Parenthesis

exponents

multiply

divide

add

subtract

in that order.

you look at number one and see that there are parenthesis which is sep one

so you add 4+5

whic is 9

now you have

6-2(9)+6

then you look and see that there are no exponents so you move on and see that there is multiplication

you must multiply 9 times -2 whic his -18

you now have:

6-18+6

next is addition

you add 18+6 which is 24

you now have 6-24

when you are subtracting a lrge number from a smal number the best thing to do is turn the larger number into a negative and add

meaning  instead of doing 6-24

you can do 6+ -24

which is -18

answer: -18

Question 2: Use pemdas again.

parenthesis is step one so you look in the parethesis and see and exponent 3 to the second which is 9 +2 which is 10

now you have 5-2 X 3+6 (10)

multiplication is next

so you multiply -2 times 3

which is -6

you now have 5 - 6 +6 (10)

her is still more to mu;tiply

you multiply 10 times 6 which is 60

you now have 5-6+60

next you add

6+60 is 66

now you have 5-66

again we change it too 5+ -66

ANSWER: -61

Answer 2

PEMDAS

Parens, Exponents, Multiply/Divide, then Add/Subtract.

5 - 2·3 + 6(3² + 1)

Do the inside of the parens first.  Inside that, do exponents first.  3² is 9, so…

5 - 2·3 + 6(9 + 1)

Do the inside of the parens first.  So…

5 - 2·3 + 6(10)

Now, simplify out the parens:

5 - 2·3 + 6·10

Start on multiply and divide, left to right:

5 - 6 + 6·10

5 - 6 + 60

Last, do add and subtract, left to right:

-1 + 60

59

Answer 3

Firsly, you need to know the order of operations (the order in which we do calculations:

BIDMAS; Brackets, Indices (powers), Division, Multiplication, Addition, Subtraction

Now , let's start

1. 6 - 2 x 9 + 6

    6 - 18 + 6

        18

2. 5 - 2 x 3 + 6 (9+1)

    5 - 2 x 3 + 6 x 10

    5 -    6   +   60

          59

Answer 4

first

6-2*9+6

=-6

in second

5-6+60

=59

Answer 5

Start with the insides of parentheses, then go in the order you've learned.

6 - 2(4 + 5) + 6

= 6 - 2(9) + 6

= 6 - 18 + 6 = -12 + 6 = -6

5 - 2 * 3 + 6(3^2 + 1)

= 5 - 2 * 3 + 6(9 + 1)

= 5 - 2 * 3 + 6(10)

= 5 - 2 * 3 + 60

= 5 - 6 + 60 = -1 + 60 = 59
