7 the number

For each of the seven rows, insert the mathematical symbols (+, -, ÷, ×) that will make the equation correct for someone calculating from left to right. no need to use paranthesis. Here's an example with the symbols already inserted:
7 × 7 - 7 ÷ 7 = 6

7 7 7 7 = 9
7 7 7 7 = 15
7 7 7 7 = 56
7 7 7 7 = 63
7 7 7 7 = 91
7 7 7 7 = 147
7 7 7 7 = 294

7 + 7 ÷ 7 + 7 = 9
7 ÷ 7 + 7 + 7 = 15
7 ÷ 7 + 7 × 7 = 56
7 × 7 + 7 + 7 = 63
7 + 7 × 7 - 7 = 91
7 + 7 + 7 × 7 = 147
7 × 7 - 7 × 7 = 294

  1. 7+7/7+7=9
    7/7+7+7=15
    7/7+7*7=56
    7*7+7+7=63
    7+7*7-7=91
    7+7+7*7=147
    7*7-7*7=294
