Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
321 * 3 * 236 * 5 * 248 * 4 * 20 = 384
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. +, -, ×, +, ÷, ×.
Given equation: 321 * 3 * 236 * 5 * 248 * 4 * 20 = 384
Mathematical signs to sequentially replace the * signs:
321 + 3 - 236 × 5 + (248 ÷ 4) × 20 = 384
321 + 3 - (236 × 5) + (62 × 20) = 384
321 + 3 - 1180 + 1240 = 384
1564 - 1180 = 384
384 = 384
