Exponentiation 1.A1  2 A2  3 A3  =A1^A2 B1  =2^4 2.^ for exponentiation

ROUND Function 1.Round a number to a specified number of digits. 2.A1  15.4876 A2  =ROUND(A1,3) A3  =ROUND(A1,2) A4  =ROUND(A1,1) A5  =ROUND(A1,0) B1  12.5 B2  =ROUND(B1,0) B3  13.5 B4  =ROUND(B3,0) B5  =ROUND(12.875,2) B6  =ROUND(12.865,2)

ROUND Function 1.Insert menu, Function menu item, 2.Select category as Math & Trig 3.Select ROUND function and click ok 4.Select values to num and num_digits fields 5.Click ok =ROUND(AVERAGE(A1:A5),0)

INT Function 1.Rounds a number down to the nearest integer. 2.A1  12.25 A2  =INT(A1) A3  =INT(12.45) A4  =INT(13.689) 3. Insert menu, Function menu item, 4. Select category as Math & Trig 5. Select INT function and click ok 6. Select value to number field 7. Click ok

MOD Function 1.Returns the remainder after a number is divided by a divisor. 2.A1  10 A2  3 A3  =MOD(A1,A2) A4  =MOD(5,2) A5  =MOD(3,4) A6  =MOD(4,3) 3. Insert menu, Function menu item, 4. Select category as Math & Trig 5. Select MOD function and click ok 6. Select values to number and divisor fields 7. Click ok

IF Function 1.Checks whether a condition is met, and returns one value if TRUE, and another value if FALSE. =IF(CONDITION,TRUE Value, FALSE Value) A1  45 A2  50 A3  65 B1  =IF(A1>=50,”PASS”, “FAIL”) B2 to B3  drag formula in B1 3.= equals to 4.<> not equals to 5.< less than 6.> greater than 7.<= less than or equals to 8.>= greater than or equals to

IF Function 1.Insert menu, Function menu item 2.Select category as Logical 3.Select IF function and click ok 4.Select values to logical_test, value_if_true and value_if_false fileds 5.Click ok

Nested IF Functions 1.A1  MARKS A2  40 A3  50 A4  60 A5  70 A6  80 A7  90 B1  GRADE B2  =IF(A2>=75,”A”,IF(A2>=65,”B”,IF(A2>=55,”C”,IF(A2>=55,”S”,”F”)))) B3 to B7  drag formula in B2

Nested IF Functions 1.A1  MARKS A2  40 A3  50 A4  60 A5  70 A6  80 A7  90 B1  GRADE B2  =IF(A2<45,”F”,IF(A2<55,”S”,IF(A2<65,”C”,IF( A2<75,”B”,”A”)))) B3 to B7  drag formula in B2
