Here are the solutions for the addition problems on the worksheet. I have calculated each sum carefully, making sure to carry over numbers when the ones column adds up to 10 or more.
Row 1:
* $91 + 62 = 153$
* $21 + 52 = 73$
* $12 + 31 = 43$
* $31 + 59 = 90$ (Carry the 1 from $1+9=10$)
Row 2:
* $53 + 91 = 144$ (Carry the 1 from $3+1=4$... wait, $3+1=4$, no carry. $5+9=14$. Result 144.) *Correction: Let's re-verify.* $3+1=4$. $5+9=14$. Answer is 144.
* $82 + 16 = 98$
* $48 + 73 = 121$ (Carry the 1 from $8+3=11$)
* $42 + 48 = 90$ (Carry the 1 from $2+8=10$)
Row 3:
* $25 + 69 = 94$ (Carry the 1 from $5+9=14$)
* $23 + 12 = 35$
* $27 + 48 = 75$ (Carry the 1 from $7+8=15$)
* $64 + 27 = 91$ (Carry the 1 from $4+7=11$)
Row 4:
* $55 + 28 = 83$ (Carry the 1 from $5+8=13$)
* $17 + 22 = 39$
* $36 + 68 = 104$ (Carry the 1 from $6+8=14$)
* $48 + 51 = 99$
Final Answer:
Row 1: 153, 73, 43, 90
Row 2: 144, 98, 121, 90
Row 3: 94, 35, 75, 91
Row 4: 83, 39, 104, 99
