Question

Simplify by using order of operations: 4 + (9∙2) ÷ (4 - 1) - 4

Answer 1

Answer: 6

Step-by-step explanation:

4+(9 x 2) / (4-1)-4=6

Calculate within parentheses (9 x 2) : 18

= 4+18 / (4-1) -4

Calculate within parentheses (4-1) : 3

=4+8 / 3-4

Multiply and divide (Left to right) 18 / 3 : 6

= 4+6-4

Add and subtract (left to right) 4+6-4 : 6

=6

Answer 2

Answer:

20

Step-by-step explanation:

Use PEMDAS

P = parenthesis

E = Exponents

M = Multiplication*

D = Division*

A = Addition**

S = Subtraction**

*either can come first, it just depends which comes first in the equation.

**either can come first, it just depends which comes first in the equation.

Step 1 : Write equation   4( 9 × 2 ) ÷ ( 4 -1 ) - 4

Step 2: Solve in parenthesis   4(18) ÷ (3) - 4

Step 3: Solve multiplication   72 ÷ 3 - 4

Step 4: Solve division               24 - 4

Step 5 : Solve subtraction         20
