570 + 54 = 624
570 + 480 = 1,050
570 ^ 500+70 ^ ^ 250+250+70
2 kg plus 570 grams = 2.57 kg or 2570 grams
11 + 694 - 54 + 497 + 54 = 1202
54 ÷ 6 + 36 + 9 = 54
54 + 3 + 10 = 67
It is: 126 plus 54 = 180
1 + 54 + 23 + 23 + 43 = 144
-154 + 54 = 54 - 154 = -100
54 + 560 + 90 = 704
45 + x + 54 + x 2x + 99
The answer = 4580
