How do you simplify #1-7-(2*2 ) + 6*2#?

Answer 1

The problem here is to get the proper order of operations. A mnemonic: PEDMAS, which should probably be written PE(DM)(AS), is often offered as a way to remember the order.

#1-7-(2*2)+6*2#
Evaluate contents of parentheses #=1-7-4+6*2#
There are no Exponents, so go on to Division and Multiplication (there is only one) #=1-7-4+12#
We are only left with Addition and Subtraction which are operations at the same level so they are performed from Left to Right #=(-6)-4+12#
#=(-10)+12#
#= 2#

#2#

Count the number of terms. Each term must simplify to give a single answer which will be added or subtracted in the LAST line.

#color(red)(1)color(blue)(-7)color(magenta)(-(2xx2))color(green)(+6xx2)" there are 4 terms"#
=#color(red)(1)color(blue)(-7)color(magenta)(-4)color(green)(+12)#

It is probably easier to re-arrange the terms with the additions first

=#color(red)(1)color(green)(+12)color(blue)(-7)color(magenta)(-4)#
=#2#

Answer 3

To simplify the expression (1 - 7 - (2 \times 2) + 6 \times 2), follow the order of operations, which is parentheses, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, perform the operations inside the parentheses: [2 \times 2 = 4]

Now, rewrite the expression with the simplified term: [1 - 7 - 4 + 6 \times 2]

Next, perform multiplication: [6 \times 2 = 12]

Now, rewrite the expression with the simplified term: [1 - 7 - 4 + 12]

Now, perform addition and subtraction from left to right: [1 - 7 = -6] [-6 - 4 = -10] [-10 + 12 = 2]

Therefore, the simplified expression is (2).

Answer 4

To simplify the expression 1 - 7 - (2 * 2) + 6 * 2, follow the order of operations, which is parentheses, multiplication and division (from left to right), and then addition and subtraction (from left to right).

1 - 7 - (2 * 2) + 6 * 2 = 1 - 7 - 4 + 12

Now perform the subtraction and addition from left to right:

1 - 7 - 4 + 12 = -6 - 4 + 12

= -10 + 12

= 2

Therefore, the simplified expression is 2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
