If ‘–’ stands for ‘addition’, ‘÷’ for ‘multiplication’, ‘×’ for ‘subtraction’ and ‘+’ for ‘division’, then which of the following is correct ?A 25 × 12 – 14 ÷ 4 + 6 = 16 B 25 – 12 + 14 ÷ 2 × 4 = 15 C 25 – 15 + 5 ÷ 4 × 16 = 21 D 25 + 11 – 4 ÷ 10 × 6 = 20

When adding or subtracting fractions, add or subtract the

According to the order of operations, which of the following is true?Addition is done before subtraction.Addition and subtraction are done at the same time, from right to left.Addition and subtraction are done at the same time, from left to right.Subtraction is done before addition.

Arithmetic OperationsWe can also perform basic mathematical operations with numbers.int a = 6;int b = 3;Use + for addition: System.out.println(a + b); // prints 9Use - for subtraction: System.out.println(a - b); // prints 3Use * for multiplication: System.out.println(a * b); // prints 18Use / (forward slash) for division: System.out.println(a / b); // prints 2Use % (percent symbol, called modulo operator) for the division remainder: System.out.println(a % b); // prints 0 as 6 is evenly divisible by 3Use ++ for increasing the value of a variable by 1: a++; System.out.println(a); // prints 7Use -- for decreasing the value of a variable by 1: b--; System.out.println(b); // prints 2TaskTry printing the sum of 21 and 40.
