Using PEMDAS, simplify:
9*1000 + 8*100 + 7*10
Define PEMDAS:
P = Parentheses ()
E = Exponents (^)
M = Multiplication (*)
D = Division (÷)
A = Addition (+)
S = Subtraction (-)
Step 1
Simplify using Parentheses
PEMDAS → Parentheses
There are 0 Parentheses in 9*1000 + 8*100 + 7*10
We move to our next letter in PEMDAS
Step 2
Simplify using Exponents
PEMDAS → Exponent
There are 0 Exponent in 9*1000 + 8*100 + 7*10
We move to our next letter in PEMDAS
Step 3
Simplify using Multiplication
PEMDAS → Multiply
There are 3 Multiply in 9*1000 + 8*100 + 7*10
9 * 1000
This evaluates to 9000
Simplify our expression
9000 + 8*100 + 7*10
8 * 100
This evaluates to 800
Simplify our expression
9000 + 800 + 7*10
7 * 10
This evaluates to 70
Simplify our expression
9000 + 800 + 70
Step 4
Simplify using Division
PEMDAS → Divide
There are 0 Divide in 9000 + 800 + 70
We move to our next letter in PEMDAS
Step 5
Simplify using Addition or Subtraction
PEMDAS → Add/Subtract
There are 2 Add/Subtract in 9000 + 800 + 70
Simplifying our expression
Our answer is = 9870
