In Excel:A1 = 95A2 = 95A3 = 80A4 = 0=IF(A1<A2),”T”,”F”)

In Excel:A1 = 95A2 = 95A3 = 80A4 = 0=IF(A1<A2),”T”,”F”)

1.T2.F CORRECT

In Excel:A1 = 95A2 = 95A3 = 80A4 = 0=IF(AND(A3<A2,A4>0),”T”,”F”)

In Excel:A1 = 95A2 = 95A3 = 80A4 = 0=IF(AND(A3<A2,A4>0),”T”,”F”)

1.T2.F CORRECT

In Excel:A1 = 95A2 = 95A3 = 80A4 = 0=IF(OR(A1<>A2,A4<=0),”T”,”F”)

In Excel:A1 = 95A2 = 95A3 = 80A4 = 0=IF(OR(A1<>A2,A4<=0),”T”,”F”)

1.T CORRECT2.F

In Excel:A1 = 95A2 = 95A3 = 80A4 = 0=IF(AND(OR(A2<A3,A4<=0),A1>=A3),”T”,”F”)

In Excel:A1 = 95A2 = 95A3 = 80A4 = 0=IF(AND(OR(A2<A3,A4<=0),A1>=A3),”T”,”F”)

Variables in Excel are kept in cells, addressed by cell addresses (not names as in Matlab)Like Matlab, Excel has a built-in IF statementExcel simulates loops by multiple rows
