Breaking down the steps:

  • ⇒ sin(30+log(10)
  • ⇒ sin(30+log(10), where log(10) equals 1
  • ⇒ sin(30+1)
  • ⇒ sin(31)
  • ⇒ sin(31) = 0.5150380749

⇒ It is important to ensure that you close brackets where necessary, as failing to do so may result in a different answer.

sin(30) – log(10) = -0.5
log(10) – sin(30)= 0.5
Multiplication (×)
To multiply two numbers or functions, you can follow the same steps as addition, but with a sign change.Example: 5 × 6 = 30
Example: 5 × (-6) = -30
Example: (-5) × 6 = -30
sin(30) × log(10) = 0.5 × 1= 0.5
log(10) × (-sin(30))= 1×(-0.5) = 0.5
 Division (÷)
To divide two numbers or functions, you can follow similar steps as mentioned for addition and multiplication, but with a sign changeExample: 30 ÷ 6 = 5
Example: 30 ÷ (-6) = -5
Example: (-30) ÷ 6 = -5
log(10) ÷ (-sin(30))= 1÷(-0.5) = -2
