KNOCK KNOCK

1 ... LET

ASSUME THAT NUMBER IS X

LESS MEANS -

IS MEANS EQUAL TO =

X - 20 = 80

X = 80+20

X= 100

IF MINUS COMES TO RIGHT SIDE WE HAVE TO CHANGE THE SYMBOL +

2.....LET

ASSUME X IS A NUMBER

FROM MEANS

X-60=48

X=48+60

X=108

3....LET

ASSUME X IS A NUMBER

TIMES MEANS ×

8X=32

X = 32/8

X = 4

IF MULTIPLE COMES TO RIGHT SIDE WE HAVE TO CHANGE SYMNOL ÷

4...LET

X + 43 = 352

X = 352-43

x = 309

YOU CHECK THE EQUATIONS BY SUBSTITUTING THE NUMBER AT THE PLACE OF X
