Practicing Success
If ‘+’ stands for ‘multiplication’, ‘<’ stands for ‘division’, ‘÷’ stands for ‘subtraction’, ‘–‘ stand for ‘addition’ and ‘×’ stands for ‘greater’ than. Identify which expression is correct? |
20 – 40 + 4 + 8 < 2 × 26 20 × 8 + 15 < 5 ÷ 9 - 8 20 < 2 + 10 ÷ 4 – 6 × 100 20 < 5 + 25 ÷ 10 – 2 × 96 |
20 < 2 + 10 ÷ 4 – 6 × 100 |
For every type of Mathematical operations question, you must know only one rule i.e. BODMAS. It is “Brackets, Orders, Division, Multiplication, Addition, and Subtraction. It means you must solve any equation in the BODMAS order. First, open the brackets, then solve the powers or roots, then perform Division followed by multiplication, Addition and subtraction. In this question, we replace signs according to the question. Using the given symbols, we have: Given expression: 20 ÷ 2 × 10 – 4 + 6 > 100 = 10 × 10 – 4 + 6 > 100 = 106 – 4 > 100 = 102 > 100. |
