624 + 813 = 1437
324 + 624 = 948
570 + 54 = 624
203 +421 _____ 624
624 = 624/1
It helps to have some brackets to know what the order is, without them we will use the order of operations and do the multiplication first 8x78=624 40-624+9= -575
24 = t + 624 - 6 = t +6 - 618 = t
624-379 = 245
624 and divide28 = 22.285714285714285
