Math: Addition (Plus sign +)

I. Addition  (+)   Equal sign  (=)

1+1= 2       2+2  = 4         3+3= 6

1+2 = 3      2+3  = 5                 3+4= 7

1+3 = 4      2+4  = 6                 3+5= 8

1+4 = 5      2+5  = 7                 3+6= 9

1(one) plus(+) (one) =(equals) 2

1+1=2

Math: Addition (Plus sign +)

I. Addition  (+)   Equal sign  (=)

1(one) plus(+) (one) =(equals) 2

1+1=2

101+101= 202     432+432 = 864           123+123=246     1000+1000=2000      12,343+10,000 = _________________________ 

II. Subtraction  (-) minus sign

I. Subtraction  is done by deducting number (subtrahend)  from the other number(minuend

7(seven)-(minus) 5 (five) = (equals ) 2

10-1=9            20-10=10                30-15=15

9-2=7            20-9=  11        30-14=16

9-3=6            20-8=  12        30-13=17
