**Equations, Expressions & Toys**

Question 1.

Fill in the missing numbers to solve these addition equations.

50 + 40 + 10 = _________

60 + 4 + _________ = 74

50 + _________ + 9 = 79

80 = 40 + 30 + _________

20 + _________+ 20 = 60

_________ + 30 + 20 = 100

Answer:

50 + 40 + 10 = **100**

60 + 4 + **10** = 74

50 + **20 **+ 9 = 79

80 = 40 + 30 + **10**

20 + **20 **+ 20 = 60

**50** + 30 + 20 = 100

Explanation:

The given addition equations are solved to fill the given missing numbers.

Question 2.

Fill in the missing numbers to solve these subtraction equations.

60 – _________ = 40

75 – _________ = 25

120 – 60 = _________

100 – 30 = 20 + _________

90 – 40 = 25 + _________

_________ – 40 = 20 + 30

Answer:

60 – **20** = 40

75 – **50** = 25

120 – 60 = **60**

100 – 30 = 20 + **50**

90 – 40 = 25 + **25**

**90** – 40 = 20 + 30

Explanation:

The given Subtraction equations are solved to fill the given missing numbers.
