Answer 1

Answer:

Using brackets , write three pairs of numbers whose sum is 10. Use them to write three equalities

ans : (5+5)=(7+3)=(6+4)

Using brackets, write three pairs of numbers whose difference is 6. Use them to write three equalities.

ans : (10-4)=(9-3)=(7-1)

Say right or wrong:

(23+4)=(4+23) right

(9+4)<4. wrong

(4x7)=30-2. right

(16+0)=16. wrong

4) Fill in the blanks:

(1x7) = (_7_x1)

(48÷3) < ( 4_x5)

(0+1) > (5x_0_)

(35÷7) = (__2_+__3_)

5) Use letters for 'any number' and write the following properties in short:

The sum of any number and zero is the number itself.

(a + 0) = a

The product of any two numbers and the product obtained after changing the order of those

numbers is the same.

(a x b) = (b x a)

The difference between any number and zero is the number itself.

(a - 0) = a
