Can you me what i did wrong and me solve this equation

Remark

The order is not quite correct.

-  7 + (-11 * 5 - - 7) ÷ - 6

The - - 7 becomes a plus

- 7  + (- 55 + 7) ÷ -6      

This is where the real problem is. -55 + 7 goes down. This gives - 48

- 7 + [( - 48) ÷ - 6]

You do  the division by - 6 before adding. Adding - 7 to the result of the division is your very last step. Think BedMas.

-7 + (8)

The 8 is the result of the division. -48/-6 = 8. the -7 and the 8 are added. You get 1.

The --7 in parentheses means +7. The symbol "÷" means "divided by". Division is done before addition or subtraction.

Whenever an even number of minus signs is involved in multiplication or division, the result is a positive number. An odd number of minus signs results in a negative number.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
